Question

One angle of a triangle is 60°. The other two angles are in the ratio of 5:7. Find the two
angles​

Answer 1

Answer:

50° ,70°

Step-by-step explanation:

let common multiple of the ratio be x

therefore, angles= 5x, 7x

by angle sum property of triangle

5x+7x+60°=180°

12x=180-60

12x= 120°

x= 10°

so, angles of triangle are=60°, 50°, 70°
