Question

In a triangle XYZ the angles are in the ratio of 1: 3:5
Find the measure of each angle.​

Answer 1

Angles are 20°, 60° and 100°

Explanation:

Ratio= 1:3:5

Let the common no. be x

Therefore, angles of triangle are x,3x,5x

1x+3x+5x= 180° (Angle sum property)

9x= 180°

x= 180°/9

x= 20°

3x= 3(20°)= 60°

5x= 5(20°)= 100°

Answer 2

Answer:

1x + 3x + 5x = 180°

9x = 180°

x = 180°/9

x = 20°

3x = 60°

5x = 100°
