The angles in A triangle are such that one is 128° more than the smallest angle, while the third angle is two times as large as the smallest angle. Find the measure all three angles.

Respuesta :

Let x degrees be the measure of the smallest angle. Then, since the 3 angles in a triangle add up to 180 degrees:-

x + x + 128 + 2x = 180

4x = 180 - 128 = 52

x = 13 degrees

The measure of the 3 angles is 13, 26 and 141 degrees (answer)
