Question

Given isosceles triangle ABC with AB = BC. If angle A= 2x + 10 and angle B = 6 - 20, then angle C = ?

Answer 1

Answer:

C= 2x+10

Step-by-step explanation:

The congruent legs: AB = BC

The congruent base angles: angle A and angle C

Vertex angle: angle B

Since it's an isosceles triangle, there will be two legs equal to each other meaning there will also be two angles of the triangle equal to each other (the base angles).
