Question

Find the value of x in the following figure.​

Answer 1

Answer:

x = 40

use sum of interior opposite angle property

Answer 2

Let triangle be ABC

where A= x , B= right angle (90°) and c = y

130 + c = 180

130 + y = 180

y = 180 - 130

y = 50

SO ANGLE C = 50

Now ,

By angle sum property of triangle ABC

Angle A + Angle B + Angle C = 180

Put value of each angle

x + 90 + 50 = 180

140 + x = 180

x = 180 - 140

x = 40

Hence , value of x is 40
