If the two congruent angles (angles A and B) of an isosceles triangle are each twice the third, non-equal angle. (angle C)
find the measure of the non equal angle, angle C.

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
