Question

In the figure shown, which is the value of y?

A 15
B
(2y)
18
C 36
(x)⁰
D 72
(3x)
(2y)

Answer 1

The answer is B

18°

Explanation:

3x+x+x=180

5x=180

divide both sides by 5

5x/5=180/5

x=36°

3x=empty space(vertically opposite angles)

2y+2y+3x=180(angles on a straight line

4y+3(36)=180

4y+108=180

4y=180-108

4y=72

divide both sides by 4

4y/4=72/2

y=18°
