Enter Angle Ratio
A triangle contains angle ratio of:
3:5:7
Find the angle measurements
Triangle Angle Sum Formula
Angle sum of a triangle = 180°
Set sum of our angle values = 180
3x + 5x + 7x = 180
15x = 180
Divide each side by 15
| 15x | |
| 15 |
| = |
| 180 |
| 15 |
x = 12
Plug in x = 12
Angle 1 = 3 x 12 = 36°
Angle 2 = 5 x 12 = 60°
Angle 3 = 7 x 12 = 84°
Angle 1 = 36
Angle 2 = 60
Angle 3 = 84
Angle 2 = 60
Angle 3 = 84
