Question

the angle of triangle are in the ratio 1 : 3 : 5 find the measure of each of the angle
i​

Answer 1

Consider 1 : 3 : 5 as 1x , 3x , 5x

we know that sum of all angles in a triangle is 180°.

x + 3x + 5x = 180°

9x = 180°

x = 20°

1x = 20°

3x = 3×20 = 60°

5x = 5×20 = 180°

Answer 2

Answer:

Let each side be x.

1x +3x + 5x =180°

9x=180°

x= 180/9

x=20°

1x= 1*20 =20°

3x= 3*20 =60°

5x= 5*20 =100°
