Question

The second angle of a triangle is 3 times as large as the first angle. The third angle is 30 degrees more than the first angle. Find the measure of the angles.

Answer 1

30-60-90 degrees

Explanation:

1st angle: x

2nd angle: 3x

3rd angle: x+30

Sum of all angles must be 180 degrees

x + 3x + x + 30 = 180

5x + 30 = 180

5x = 150

x = 30
