Question

$find \: x \: in \: the \: figure$
​

Answer 1

Answer:

2y + 2y + 5y = 180° (Linear Pair)

4y + 5y = 180°

9y = 180°

y = 180° ÷ 9

y = 20°

2y = 2 × 20°

= 40°

x + 40° + 40° = 180° (Linear Pair)

x + 80° = 180°

x = 180° - 80°

x = 100°

Hence, the value of x equals to 100°

Hope it helps

Answer 2

X should be 5y. Vertically opposite
The angle left should be 4y. Vertically opposite
The value of y is
5y+4y+5y+2y+2y=360. Complete revolution
18y=360
y= 360/18
=20
So the value of X will be 5*20=100 degree
