Answer 2

Step-by-step explanation:

From the triangle ABC

Consider ∠A=60∘ ,∠B:∠C=5:7

In a triangle ∠A+∠B+∠∠C=180∘

Substituting the values

60° +∠B+∠C=180 °

By further calculation

∠B+∠C=180∘

–60°

=120°

Take ∠B=5x and ∠C=7x

Substituting the values

5x+7x=120°

12x=120°

x=120°

/12=10°

So we get

∠B=5x=5××10 ° =50∘

∠C=7x=7××10° =70∘
