Question

The angles of a triangle are such that one angle is 100 degrees more than the smallest angle, while the third angle is 2 times as large as the smallest angle. Find the measure of all three angles.

Answer 1

20, 40, 120

Explanation:

Smallest angle = x

Second angle = x + 100

Third angle = 2x

4x + 100 = 180

4x = 80

x = 20

20, 120, 40
