Question

In the given figure, if AB = AC, then find the value of x.
​

Answer 1

Answer:

70° is answer

let , angle b = x

180° - 125 ° = 55°

if ab = ac

then angle c = 55°

sum of all angles of triangle = 180 °

then

55° + 55° + x = 180°

x = 180 ° - 110 °

x = 70°

Answer 2

Answer:

70° is the correct answer

Step-by-step explanation:

Given- AB=AC

To find- value of x

solution - let take equal angle is y

therefore, 125°+y = 180°. ( by linear pair angle)

y=180-125

y=55°

by angle some property

A+B+C=180

therefore, x+55°+55°= 180°

x=180-110

x=70°

the value of x is 70°
