Question

The angle of a tringle are in the ratio 1 : 3 : 5. Find The measure of each of the angles.

Answer 1

let the angles be x 3x and 5x
then x+3x+5x=180
9x=180
x=20
second angle=60
100

Answer 2

hey there!!

Solution:-


let the common ratio be x

then, first angle= x

second angle = 3x


third angle=5x

As we know that,

sum of angles of a triangle = 180°
x+3x+5x=180°

9x=180
x=20°



so,first angle=x=20°

second angle = 3x=3×20=60°


third angle=5x=5×20=100°
