Question

In the figure line l and line m intersect at point o. ∠AOD= y° ∠AOB =2x² ∠DOC= (3x-50°) then the value of x is ​
A) 50°
B) 130°
C) 80°​

Answer 1

so let's start

2x=3x-50 (V.o.a.)

3x-2x=50

x= 50

option a

btw voa is vertically opposite angle

plZ make me the brainliest

Answer 2

To find:-

• Value of x

$\huge \tt \: ☃Solution$

⠀⠀⠀⠀⠀

If line l intersecting line m.

So,

⇒3x° - 50° = 2x° ( Vertically opposite angle)

⇒3x° - 2x°= 50°

⇒x = 50°

⠀⠀⠀⠀⠀

⇒y + 2x = 180° ( Linear pair)

⇒y + (2 × 50°) = 180°

⇒y + 100° = 180°

⇒y = 180° - 100°

⇒y = 80°

⠀⠀⠀⠀⠀

Thus, the value of x is 50°
