Question

the angles of a triangle are in the ratio 1 ratio 3 ratio 5 ratio 3 find the measure a speech one of the angles​

Answer 1

let the ratios be x,3x,5x

x + 3x + 5x= 180° (angle Sum property of a triangle)

9x = 180

x = 180/9

= 20°

therefore, each angle = 20°

so, angle 1= 20°

angle 2= 3 x 20=60°

angle 3= 5 x 20 = 100°

Answer 2

sum of angles in triangle =360°

ratio parts =1:3:5:3

=1x+3x+5x+3x

=12x

12x=360°

x=360°/12

x=30°

1x=30°

5x=150°

3x=90°

3x=90°
