Question

In an isosceles triangle, the base angles are equal. The vertex angle is 40°. What are the

base angles of the triangle?​

Answer 1

Answer:

base angles = 70°

Step-by-step explanation:

The vertex angle is 40°

Let the base angles be x (Base angles are equal)

2x + 40° = 180°

2x = 180° - 40°

2x = 140°

x = 140/2

x = 70°
