Question

In angle ABC angle B = angle C and angle A =80 digre. Find angle B and angle C​

Answer 1

Answer:

Step-by-step explanation:

given,

AB is a triangle

AB=AC

AngleA=80

angleB=angleC (angles opposite to equal sides are equal)

angle(A+B+C)= 180 (sum of angles in triangle)

80+x+x=180

2x=180-80

2x=100

x=100/2

x=50

angle(B=C)=50

Answer 2

Given

angle B = angle C

angle A = 80°

A/ C

80° +angle B + angle C = 180°

or, 80° + 2angle B = 180° ( as angle B = C)

or, 2angle B = 100°

or, angle B = 50°

As angle B = C = 50°
