Question

In triangle ABC, if AB =AC and ∠B =76 , then ∠A = ​

Answer 1

Answer:

Angle A= 28

Step-by-step explanation:

if AB=AC

then angle B= angle C

which means angle A= 180-152= 28

Answer 2

Step-by-step explanation:

In ∆ABC

AB=AC

angle ABC=76°

In ∆ if two side are equal then opposite angles are also equal

so,

angle ACB=76°

In ∆ABC

Angle ABC+ angle ACB+ Angle BAC=180°

76°+76°+ angle ACB =180°

Angle ACB= 180°- 152°

Angle ACB= 28°

Angle A= 28°
