Question

In a triangle ABC, sides AB and AC are equal length. If angle B =

35, find the measure of angle A and angle C​

Answer 1

Answer:

In ∆ ABC ,

Side AB = Side AC

Angle B = 35

By Isosceles triangle theorem ,

Angle C = Angle B

= 35

Angle C = 35

Now,

Angle A + Angle B + Angle C = 180°

Angle A + 35 + 35 = 180

Angle A + 70 = 180

Angle A = 180 - 70

Angle A = 110
