Question

18. Who among the following persons comes with his/her strong recommendation to appoint Sidda ?
(a) Mr. Sivasankar(b) the wife of Mr. Sivasankar
(c) Leela (d) nobody​

Answer 1

Answer:

A−B=15∘           

B−C=30∘

B=C+30∘           

On adding both equation, we get

A−C=45∘

A=C+45∘           

In a triangle,

A+B+C=180∘         

Substituting the value from equation (1) and (2), we get

C+45∘+C+30∘+C=180∘

3C=105∘

∠C=35∘.

Substituting this value in equation (1) and (2), we get

∠B=65∘

∠A=80∘

Hence, the angles are ∠A=80∘ ∠B=65∘  ∠C=35∘.
