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

Answer:
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°
