In a triangle and . Then the measure of is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
Given: ab=2+3 ∠C=60° Also, A+B+C=180° ⇒A+B=120° ...1 By sine formula sinAa=sinBb ⇒sinAsinB=ab ⇒sinAsinB=2+3 Applying Componendo and Dividendo, we get sinA+sinBsinA-sinB=3+33+1…
