Question

The ratio of the measure of a base angle in an isosceles triangle to the measure of the vertex angle is 2:16. Find the measure of each angle.

Answer 1

The third angle - the other base angle - must be in the same ratio.

2 : 2 : 16

 

2x + 2x + 16x = 180

 

Can you solve for x and answer?
