Which equation can be used to solve for in the following diagram?
Choose 1 answer:
А) 105 + (50 – 70) = 90
B) 105 + (5x – 70) = 180
C) 105 = (5x – 70)
D) 105 +90 = (5x - 70)
Answers
Answer:
C) 5x-70=105
Step-by-step explanation:
As marked in the graph, angle 105 and angle (5x-70) equal to each other because they are vertically opposite angles therefore we have equation C)
C) 105 = (5x – 70)
Seems correct

A decorator is wallpapering a wall with a circular window of diameter 1.00 m.What is the
area of the wall in square feet? (1 m - 3.2808 feet)
3
Answers
Answer:
95.875 [tex]ft^{2}[/tex]
Step-by-step explanation:
1.) Calculate the area of the trapezoid
A(trapezoid) = (1/2)*(base1 + base2)*h = (1/2)*(2.6+3.6)*3 = (1/2)*6.2*3 = 9.3
2.) Calculate the area of the circle
radius = (1/2)*(diameter) = (1/2)*1 = 0.5
A(circle) = (1/2)*[tex]\pi[/tex]*[tex]r^{2}[/tex] = (1/2)*[tex]\pi[/tex]*([tex]0.5^{2}[/tex]) = (1/2)*[tex]\pi[/tex]*0.25 = 0.125*[tex]\pi[/tex] = 0.392699
3.) Because the area of the circle is not included in the wall, subtract the area of the circle from the area of the trapezoid:
A(trapezoid)-A(circle) = 9.3-0.392699 = 8.9073 [tex]m^{2}[/tex]
4.) Convert to [tex]ft^{2}[/tex]:
Because 3.2808 feet are in a meter and the unit of the answer is in [tex]m^{2}[/tex], we need to multiply the answer by ([tex]3.2808^{2}[/tex]) to get to [tex]ft^{2}[/tex].
8.9073*([tex]3.2808^{2}[/tex]) = 8.9073*10.7636 = 95.875 [tex]ft^{2}[/tex]

Answer:
A. 223 were not playing volleyball
B. 12 books on each shelf with 3 books left over..
C. 12.15$ a day
D. 12.15 miles per day.
Step-by-step explanation:
A. Subtract 20 from 243.
B. Since books cant be divided into fractions, you take 243 divided by 20, which is 12.15. However, we have to say 12 with 3 leftover because books isn't money, a distance measure, etc. and cannot be cut into pieces.
C. 243 / 20 is 12.15
D. 243 / 20 is 12.15

a circle has a diameter of 18. the sector has a central angle of 30 degrees. what is the area of the sector?
Answers
Answer:
21.21
Step-by-step explanation:
Area of a circle is A = π r^2
Variables:
r = 18/2 = 9
θ = 30 deg
Find the area:
A = π r^2
A = π 9^2
A = 254.47
Find the area of the sector:
θ/360 * A
= 30/360 * 254.47
= 21.21

The measure of ∠CBD is 45% of the measure of ∠ABC. Find the value of x.
Answers
Answer:
x = 49.5°
Step-by-step explanation:
∠ABC = 90°
∠CBD = 45%∠ABC
∠CBD = 0.45(90)
∠CBD = 40.5°
x = ∠ABC - ∠CBD
x = 90 - 40.5
x = 49.5°

Answer:
the second, and fourth one's are triangles, and the 1st and 2nd are not
Step-by-step explanation:
We know that the angles in a triangle add up to 180 degrees. So we need to find which angles add up to 180 degrees. We have:
56+34+42=132
That means the first one can't be a measures of a triangle.
75+55+50=180
Second one is a triangle.
35+32+23=90
Third isn't a triangle
124+64+16=180
So all in all, the second, and fourth one's are triangles, and the 1st and 2nd are not
