Answer:
60 degrees each
Step-by-step explanation:
For the triangle, the sum of the interior angles is equal to the exterior
Let x and y be interior
Let z be the third angle
w be the exterior
w = x+y
120 = x+y
If the exterior angle is twice of each of the interior remote angles, then;
2x = 2y
x = y
120 = x+x
2x = 120
x = 60
Since x = y, y = 60 degres
From the triangle, the third angle will be 180 - 120
z = 180-120
z = 60
The measures of the 3 angles are 60 degrees each
