Answer:

36, 60 and 84 degrees.

Step-by-step explanation:

The 3 angles add up to 180 degrees so we have the equation:

3x + 5x + 7x = 180

15x = 180

x = 12.

So the angles are

3*12 = 36.

5*12 = 60.

7&12 = 84.

Answer: 36° , 60° and 84°

Step-by-step explanation:

By using Angle Sum Property of a Triangle

3x + 5x + 7x = 180°

15x = 180

x = 180 ÷ 15

∴ x = 12

∴ Now ,

3x = 3 × 12 = 36°

5x = 5 × 12 = 60°

7x = 7 × 12 = 84°

∴ the measurement of each angle is 36° , 60° and 84°.
