Find the value of x.

Leona [35]

This is an isosceles triangle. Therefore, at the base we have congruent angles (look at the picture).

We have the equation:

(5x + 13)° + (3x + 7)° = 180°

5x + 13 + 3x + 7 = 180 <em>combine like terms</em>

(5x + 3x) + (13 + 7) = 180

8x + 20 = 180 <em>subtract 20 from both sides</em>

8x = 160 <em>divide both sides by 8</em>
