Question

The measure of each base angle of an isosceles triangle is seven times the measure of the vertex angle, then the measure of the vertex angle is​

Answer 1

Answer:

1/7 of each base angle

Step-by-step explanation:

let the base angle be x.

isoceles triangle = x + x + 1/7 x = 180°

= 2 whole 1/7 x = 180°

= x = 180°÷ 15/7

= x = now solve
