Question

If tan A=2 sin A .Then find the value of A.

Answer 1

Answer:

the worst topic I have ever studied

Answer 2

Answer:

Step-by-step explanation:

tan A = sin A/cos A = 2 sin A

⇒1/cos A = 2 ( sin A gets cancelled from both sides)

⇒cosA =1/2

We know that for Ф=60° cos Ф= 1/2

∴ A = 60°

Hope this helps you :)
