Answer:
x = 12
Step-by-step explanation:
it's indicated that all angles of this triangle are congruent; this means the triangle is called a 60-60-60 where all angles are 60 degrees.
If a triangle is equiangular then it is also equilateral, which means that if all angles are equal then all sides are equal.

the base of a pyramid has n sides
write an expression for the number of faces on the pyramid
Answers
Answer: The expression for number of faces of a pyramid =1+n
Step-by-step explanation:
A Pyramid is a polyhedron or a three dimensional shape having a polygon base and all lateral faces are triangles .
Its base describe the number of other faces of it.
For example a triangular pyramid has a triangular base which gives rise to 3 lateral faces , and a rectangular pyramid has a rectangular base which give rise to 4 lateral faces and so on.....
So the total number of faces in a pyramid = base + lateral faces
If a pyramid has n sides therefore it give rise to n lateral faces such that
The total number of faces in a pyramid= 1+n .

Answer:
30 square cm
Step-by-step explanation:
Key skills needed are: Triangle similarity, multiplication, proportions, subtraction
1) We first find that Triangle BCD is similar to triangle ACE. This is because they both have 1 right angle, and both share Angle BCD. Therefore, the other two angles are also the same measure.
2) Based on the statement above, 6/9 = 8/CE (CE just means the length of CE)
3) Solve this by cross multiplying -
[tex] \frac{6}{9} = \frac{8}{ce} [/tex]
This means that 6(CE) = 8(9)
4) Multiply it out: 6(CE) = 72
5) Divide by 6 and get CE = 12 cm.
6) Then use base time height to find the area of both triangles.
7) For triangle BCD: 6(8)/2 = 6(4) = 24 square centimeters
8) For Triangle ACE: 9(12)/2 = 9(6) = 54 square cm
9) To find the area of ABDE, you would subtract the are of triangle ACE by the area of triangle BCD
10) This is 54 - 24 = 30 square cm.

8x - 2y = 28
Please!! Urgent
Answers

Answer:
(x, y) = (2, -6)
Step-by-step explanation:
Subtract the first equation from the second.
(8x -2y) -(5x -2y) = (28) -(22)
3x = 6
x = 2
Substitute this into either equation and solve for y.
8(2) -2y = 28
8 -y = 14 . . . . . . . . divide by 2
y = 8 -14 = -6 . . . . add y-14 to both sides
The solution is (x, y) = (2, -6).

What is the measure, in degrees, of the angle marked B?

Answers
All triangles are 180 degrees. Add the 2 numbers given to get a number. Take 180 and subtract it from that number to get 47
Answer:
[tex]\boxed {\boxed {\sf 133 \ degrees }}[/tex]
Step-by-step explanation:
According to the Exterior Angle Theorem, the exterior angle of a triangle is equal to the sum of the 2 remote and opposite interior angle.
[tex]d=a+b[/tex]
In this triangle, angle B is the exterior angle (d). The two interior angles are 68 degrees and 65 degrees ( a and b).
[tex]\angle B=68 \textdegree +65 \textdegree[/tex]
Add.
[tex]\angle B= 133 \textdegree[/tex]
This can also be solved using triangles and supplementary angles.
The angles in a triangle must add to 180 degrees. We have three angles: 68, 65, and an unlabeled angle we can call x.
[tex]68+65+x=180 \\133+x=180[/tex]
Subtract x from both sides.
[tex]133+x=180-133 \\x=47[/tex]
x is on a straight line with B, so they are supplementary and add to 180 degrees.
[tex]47+ \angle B= 180[/tex]
Subtract 47 from both sides.
[tex]47-47+ \angle B= 180-47\\\angle B= 133[/tex]
Angle B is equal to 133 degrees.

For a triangle, any 2 side lengths of the triangle must be greatee than the 3rd side.
Given a triangle with side lengths 11, 23 and x,
we have:
11 + 23 > x,11 + x > 23, and23 + x > 11.Therefore 34 > x and x > 12. => 12 < x < 34.
Answer:
second option
Step-by-step explanation:
Given 2 sides of a triangle then the third side x is
difference of 2 sides < x < sum of 2 sides , that is
23 - 11 < x < 23 + 11, thus
12 < x < 34

what is the slope of the line that passes through (-5,0) and (-5,5)
Answers
Answer:
m=undefined
Step-by-step explanation:
the formula for slope (m) is (y2-y1)/(x2-x1)
here are the given points: (-5,0) and (-5,5)
we can label the points:
x1=-5
y1=0
x2=-5
y2=5
now substitute into the equation
m=(5-0)/(-5--5)
m=(5-0)/(-5+5)
m=5/0
m=undefined
the slope is undefined, because you cannot divide by 0
turquoise paint is made by mixing blue, green and yellow paint in the ratio 2.5 : 1.4 : 0.1 . how much of each colour is needed to make 1.5 litres of turquoise paint? write answers in the same order as the ratio (eg, blue, green, then yellow)
Answers
Answer: Blue color = 937.5 ml
green color = 525 ml
Yellow color= 37.5 ml
Step-by-step explanation:
Let the quantity of all kinds of paint required to make turquoise paint be 2.5 x(blue), 1.4 x( green), 0.1 x.(yellow).
Total turquoise color required =2.5x+1.4x+0.1x
[tex]\Rightarrow (2.5+1.4+01)x=1.5\\\\\Rightarrow\ 4x = 1.5\\\\\Rightarrow x=\dfrac{1.5}{4}\\\\\Rightarrow\ x=0.375[/tex] = 1.5 liters [given]
Blue color = 2.5 x 0.375 = 0.9375 liters = 937.5 ml [1 liter = 1000 ml]
green color = 1.4 x 0.375= 0.525 l = 525 ml
Yellow color= 0.1 x 0.375= 0.0375 =37.5 ml
A theater has 384 seats. Each row has 16 seats. The area model represents this situation. Area model showing 2 areas. The first is16 high and 20 wide, with a total of 320. The second is 16 high and x wide, with a total of 64. Part A What is the value of x in the area model? Enter your answer in the box. x = 4 I already answer part A what is the answer for part B?? Part B How many rows of seats are inside the theater? Enter your answer in the box. rows
Answers
Answer:
x=4
Rows = 24
There are 24 rows each having 16 seats making a total of 384.
Step-by-step explanation:
Part B
Total number of seats = Total of rows* Number of seats in each row
Let the total number of rows be y. The theater has 384 seats and each row has 16 seats. Putting the values
384= y * 16
y= 384/16= 24
There are 24 rows each having 16 seats making a total of 384.
Part A:
Area= length * width
Area 1= 320= 16 *20
Area 2 = 64
64 = 16 x
x= 64/16= 4
Find the value of X.

Sultan needs enough tents for 28 people to sleep in. Each tent can fit 6 people. How many tents does he need?
Answers
Answer:
5 tents
Step-by-step explanation:
1 tent = 6 people
x tent = 28 people
Cross product
1 * 28 = 6 * x
28 = 6x
x = 28/6
= 4.67
Approximately x = 5 tents to an whole number
Therefore, he needs 5 tents for 28 people to sleep in
