In then the value of
- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
Given in ∆ABC, A=75°,B=45° ⇒C=180°-75°-45°=60° (Using Angle Sum property of triangle) Also, sin75°=3+122, sin45°=12 and sin60°=32 Now, using Sine rule, asinA=bsinB=csinC ⇒a3+122=b12=c32 ⇒22a3+1=2b=2c3…
