Question

the measure of three angles are in ratio 5:3:1.find the measure of these angles

Answer 1

Let the angles be 5x , 3x and 1x .

Angle sum property of triangle = 180°

5x+ 3x + 1x = 180°

8x + 1x = 180°

9x = 180°  

  x = 180/9

x = 20°

The angles are,

5x = 5  X 20°  =  100°

3x = 3  X  20°  = 60°

1x  = 1  X  20°   = 20°
