Question

ABC is an isoseles triangle with AB=AC, /_A=50 and /_B​

Answer 1

Answer:

Let the angle B and angle C be 2x.

Total sum of interior angles of a triangle is 180°

Angle A is 50°.

2x° + 50° = 180°

2x=180-50=130°

x =130/2=65°

x=65°

Answer 2

Answer:

measure of angle B is 65°

Step-by-step explanation:
