Question

The angle of triangle are in ratio 1 : 3: 5find the measurements of each triangle​

Answer 1

Answer:

Step-by-step explanation:

Let x is including in the ratio

Then, angleA=x

angleB=3x and

angleC=5x

angleA+angleB+angleC=180°

x+3x+5x=180°

9x=180°

x=20°

angleA=20°

angleB=3×20°=60°

angleC=5×20°=100°

Plzz mark me as brainliest..

Answer 2

Sum of the angles of a triangle is 180

ratio of angles is 1 : 3: 5

sum of ratio is 9

let 1st ratio be a, 2nd ratio be b and 3rd ratio be c.

so a is 1/9 × 180 = 20 °

b is 3/9 × 180 = 60°

c is 5/9× 180 = 100°

so the angles of a triangle are 20 °,60°,100°
