Answer:

A. 69

C. 42

Step-by-step explanation:

Angle A is similar to angle C, so that makes that angle 69. With two angles figured out, we can just use basic math to find the last.

The total of all triangle angles will always be 180 degrees. Knowing this...

180-69-69=42

Thus, the angles are 69,69, and 42
