Question

the angles of a triangle are in the ratio of 1:3:5 find their mesures​

Answer 1

Answer:

Let the ratio of sides be x,3xand 5x respectively.

x+3x+5x=360°

9x=180°

x=20°

x=20°

3x=20×3=60°

5x=20×5=100°

Answer 2

Step-by-step explanation:

let the ratio be x ,

then , the angles will be x,3x and 5x.

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

so, x+3x+5x = 180

= 9x = 180

= x = 20.

hence , angles will be 20, 60 and 100
