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°.
