Question

in figure the value of x is?
wirte full step by step solution​

Answer 1

Answer: x = 130 degree

Step-by-step explanation:

Okay so we take the angle at the top calling it 'y'

110 + y = 180 (Linear pairs are = 180)

y= 70 degree

Now we take the angle in the right as 'z'

z + 120 = 180 (Linear Pairs are 180)

z= 60 degree

Now we take the third unknown angle of the triangle as 'w'

w = 180-(60+70)  (Sum of angles in a trianglel is 180)

w = 50 degree

x+w = 180 degree ( Adjacent angles aka Linear Pairs are = 180 degrees)

x = 180- 50

x= 130 degree
