If A= 60°, B =30°, then find the value of Sin A cos B + cos A sin B
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 1.
Given:
A = 60°, B = 30°
Calculations:
According to the question;
⇒ Sin 60° × cos 30° + cos 60° × sin 30°
⇒ √3/2 × √3/2 + 1/2 × 1/2
⇒ 3/4 + 1/4
⇒ 1
