The vertex angle of an isosceles triangle is 50 more than twice the base angles. Find each base angle.

Question

I have no idea how to do this and it doesn't give any direct measurements, here are the possible answers :

A)The base angles are each 100°.

B)The base angles are each 32.5°.

C)The base angles are each 30°.

D)The base angles are each 50°.

Answer 1

To answer this question you will need to use your knowledge of an isosceles triangle and the angles of the triangle... with a little help from your algebra skills.

Answer 2

An isosceles triangle has the base angles being the same.

a. 100 + 100 + 250 = 180

Nope. Keep trying.
