Question

AB is equal to AC in triangle ABC . if angle A is equal to 50 degree , find angle Band angle C

Answer 1

angle A = angle B = 50°

angle A + B + C = 180

angle C = 180 -100 = 80°

band angle = 360 - 80 = 280°

Answer 2

<A+<B+<C=180(angle sum property)

given <B=<C(AB=AC)

50°+x+x=180

50°+2x=180°

2x=180-50

x=130÷2

x=65
<B=<C=65
