Question

One of the equal angles of an isosceles triangle is 40 degree find the other angles

Answer 1

SINCE ONE ANGLE LET'S SUPPOSE
angle B = 40 degree

implies that angle C is also 40 degree

angle B + angle A + angle C = 180 degree
angle A = 180 - 80 = 100 degree

Answer 2

Answer:angle A = 40 °

Angle B =40°

Angle C = 100 °
