Question

in a triangle ABC if a b is equals to 3 cm AC is equal to 3 cm and angle A is equal to 50 degree then find the angle b

Answer 1

so angle b is equal to 50 degree because angle opposite to equal sides are equal

Answer 2

as per condition of question
this is an isoceless triangle
angle A +AngleB+Angle C=180
50+angle b+angle b=180 because angle b= anglec
2angle b=180-50
angle b=65
