Question

plzz do solve this math problem.... plzzz​

Answer 1

Step-by-step explanation:

AB=AC

THEREFORE

ANGLE B= ANGLE C

ANGLE A + ANGLE B + ANGLE C =180°

80°+ ANGLE B + ANGLE B =180°

2 ANGLE B =100°

ANGLE B =50°

Answer 2

Answer:

100

let angle B=x

80+x=180(sum of three angles of a triangle is 180)

x=180-80

x=100

soo angle B=x=100
