Angle Relationship
Find mLTSU if SU bisects LTSV,
mLTSU = 4y + 11, and m∠USV = 6y + 5.
< TSU = 4y + 11 = 23 degrees
What does angle relationship mean?
We talk of angle relationships because we are comparing position, measurement, and congruence between two or more angles. For example, when two lines or line segments intersect, they form two pairs of vertical angles
we have to find m < TSU if SU bisects < TSV, m < TSU = 4y + 11, m < USV = 6y + 5
SU bisects < TSV
=> < TSU = < USV
4y + 11 = 6y + 5
-2y = -6
y = 3
< TSU = 4y + 11 = 23 degrees ( put the value of y=3)
∠USV = 6y + 5 = 23 degrees ( put the value of y=3)
Hence ,< TSU = 4y + 11 = 23 degrees

The length of a rectangular garden is 10 feet longer than its width. The garden's perimeter is 188 feet. Find the width of the garden.
Answer: width of the garden is 42
Step-by-step explanation:
let's say "x" = the garden's length
and "y" = the garden's width
the length of the garden is 10 feet longer than its width
x-10=y
the garden's perimeter is 188 feet
we can set up a new equation like this:
2x+2y=188
now we have two equations and we can solve using the system of equations.
x-10=y
add 10 on both sides to isolate "x"
x=y+10
2x+2y=188
substitue x for y+10 in the second equation
2(y+10)+2y=188
expand
2y+20+2y=188
combine like terms
4y+20=188
subtract 20 from both sides
4y=168
divide by four on both sides
y=42
the width of the garden is 42 feet

A mural measures 95 feet long by 285 feet high. Find the ratio of the height to the perimeter of this mural.
The ratio of the height to the perimeter of this mural 57 : 152.
We are given that:
Length = 135 feet
height = 285 feet
Mural is of a rectangular shape
We will first find the perimeter.
Perimeter = 2(l + w)
Perimeter = 2(95 + 285)
Perimeter = 2(380)
Perimeter = 760 feet
We will now find the ratio of the height to the perimeter of this mural.
Height : perimeter = 285 : 760
Reduce to lowest terms
Height : perimeter = 57 : 152
Therefore, we get that, the ratio of the height to the perimeter of this mural 57 : 152.

7. There are 7 pairs of green socks, 6 pairs of white socks, 5 pairs of red socks and 4 pairs of blue socks. One person is asked to close his eyes, and draw the socks 1 pair at a time. At least how many pairs of socks should be drawn so that among the drawn socks, 4 pairs of those have the same color?
Answer:
13
Step-by-step explanation:
We can think of this as drawing 3 pairs of each color, and then the next pair will guarantee we have 4 of one color.
This is 3(4)+1=13 pairs.
Step-by-step explanation:
let me see, if I understand this right.
7 pairs of green socks = 14 green socks.
6 pairs of white socks = 12 white socks.
5 pairs of red socks = 10 red socks.
4 pairs of blue socks = 8 blue socks.
in total : 44 socks (or 22 pairs).
the person is pulling socks always 2 at a time. but each sock can be any color.
or are the pairs still connected, and each draw pulls a pair of equal socks ?
and then the question also really is, what is meant by 4 pairs have the same color ? that i find 4 groups of 2 socks each with the save color inside the group (making them pairs), or truly 4 pairs with the same color (e.g. 4 red pairs, or 4 green pairs) ?
if the pairs are still connected, only the second question makes sense.
the worst that can happen in that scenario is drawing
3 pairs of blue socks.
3 pairs of red socks.
3 pairs of white socks.
3 pairs of green socks.
this now like in Baseball : the bases are loaded. any additional runner will cause a score.
because any additional draw must complete one of the groups of 4 pairs.
so, latest after the 4×3 = 12 draws, we get a 13th draw. that gives us 4 equally colored pairs of socks for sure.
so, we need 13 draws.
if each sock is in there individually, and we still want to have 4 pairs of socks all with the same color, then it starts similarly :
the socks get pulled 2 by 2 but that means each drawn pair can have different colors of the individual socks.
in the worst case after drawing 24 socks (12 groups of 2 socks), we have the same situation as in the previous case.
but now, pulling 2 more socks does not guarantee a full set of 4 pairs. we could get 2 different socks that add only half a pair to 2 color groups.
the same with the next pulled group of 2. they fill up the other 2 color groups with half-pairs.
but now the base are loaded. by pulling the next (3rd) additional group of 4, we complete at least one color group with 4 full pairs.
so, we need 12 + 3 = 15 draws to make absolutely sure.
now, if we have individual socks, and want to get 4 pairs of socks that have just the same color inside their pair, we need to think a little bit differently.
after 2 draws (4 socks) we have in the worst case 4 individual socks with different colors.
after the next 2 draws we can be already lucky, but in the worst case we are not but have now either 2.5 full pairs of one color and 3 individual socks, or 2 full pairs in one color, 1 full pair in a second color, and 2 individual socks, or 1.5 pairs in one color, 2×1 full pairs in 2 other colors, and 1 individual sock.
with the next draw in the worst case we could only extend the second case and get 2.5 pairs in one color, 1.5 pairs in the second color and still 2 individual socks.
but now the bases are loaded, and the next draw of 2 socks guarantees that we have 4 real pairs of socks (either 3 and 1 and still 2 individual socks, or 3 and 2 pairs and 2 individual socks, or 2 and 2×1 and wherever the second sock goes, it does not matter, or any other combination where at least one of the individual socks have been combined to a pair.
so, we need
2+2+1+1 = 6 draws.

Using proportions, it is found that the total job cost for Randi is of $6,674.24.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
The total amount of square yards that she needs is given by:
111.02 + 31.82 + 161.92 = 304.76.
The cost per square yard is given by:
15.01 + 3.12 + 3.77 = $21.9.
Hence the total cost is given by:
304.76 x 21.9 = $6,674.24.

h is a trigonometric function of the form h(x) = a sin(bx + c) + d.
Below is the graph h(x). The function intersects its midline at (-4pi,2.5) and has a maximum
point at(-5pi/2,6)
Find a formula for h(x). Give an exact expression.
The expression acquired is h(x) = 3.5 sin(1/3x ₊ 4π/3)₊2.5
Given h(x) = a sin(bx ₊ c) ₊ d
The h(x) function intersects its mid line at (₋4π , 2.5)
and has its maximum points at (₋5π/2 , 6)
therefore, x₂ ₋ x₁ = ₋5π/2 ₋ (₋4π)
= ₋5π/2 ₊ 4π
= 3π/2
⇒ 2π/b = 3π/2 4
⇒ 2π/b = 6π
⇒b = 1/3
hence, a = b ₋ 2.5
a = 3.5
now h(x) = 3.5 sin(1/3x ₊ c) ₊ 2.5
x = ₋4π
h(₋4π) = 3.5 sin( ₋4π/3 ₊ c) ₊ 2.5
₋4π/3 ₊ c = 0
c = 4π/3
therefore, h(x) = 3.5 sin(1/3x ₊ 4π/3)₊2.5
hence after solving the equation we get the expression for h(x) as
h(x) = 3.5 sin(1/3x ₊ 4π/3)₊2.5
