Question

find the value of x if xoy is a straight line​

Answer 1

Answer:

x = 80°

Step-by-step explanation:

We are given,

XOY is a straight line

Hence,

∠XOY = 180°

But,

We know that,

∠XOZ + ∠YOZ = ∠XOY

(x + 15°) + (x + 5°) = 180°

x + 15° + x + 5° = 180°

2x + 20° = 180°

2x = 180° - 20°

2x = 160°

x = 160/2

x = 80°

Hence,

x = 80°

Hope it helped and believing you understood it........All the best

Answer 2

Answer:

if xoy is a striaght line then it measures 180°.

then,

x+15°+x+5°=180°(linear pair)

=>2x+20°=180°

=>2x =160°

thus , x=160°/2

x=80°
