Question

AB =AC in ∆ abc if angle A = 50 AND FIND ANGLE B AND C​

Answer 1

Answer:

Step-by-step explanation:

Here AB=AC

Therefore, angle B=angle C .....isoceles triangle theorem

In triangle ABC measure of angle A is equals to 50 degree and let angle B=angle C=x

Angle A+angle B+angle C=180... Angles of a triangle

50+x+x=180

2x=180-50

2x=130

x=130÷2

x=65°

Angle B=angle C=x=65°
