Answer:

If the third angle is x, the other two angles are 2x

 

The measure of the angles of a triangle must add up to 180 degrees

 

x + 2(2x) = 180

 

x + 4x = 180

 

5x = 180

 

x = 36

 

The other two angles are 2x = 2 * 36 = 72

 

The three angles are 36, 72, and 72 degrees

Step-by-step explanation:

EXAMPLE-

x+2x+2x=180

5x=180

x=180/5

x=36º third angle

the equal angles are each 2*36=72º
