Question

in isosceles triangle the vertex angle is twice either base angle let the base angle b is in degree remember that the sum of angle of triangle is 180 degree​

Answer 1

Answer:

Vertex angle=90° Base angle=45°

Step-by-step explanation:

Let base angle be x.

vertex angle=2x

sum of angle in a triangle=180°

4x=180°

x=180°/4

=45°

therefore,

vertex angle=90°

base angle=45°
