Find each angle measure in the triangle. 5xº (3x° 7xº The measure of the angle labeled 3x° is The measure of the angle labeled 5x° is The measure of the angle labeled 7x° is

see explanation

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180° , then

3x + 5x + 7x = 180 , that is

15x = 180 ( divide both sides by 15 )

x = 12

Then

3x = 3 × 12 = 36°

5x = 5 × 12 = 60°

7x = 7 × 12 = 84°
