Question

5cos theta=3 तो 3tan theta =?

Answer 1

Answer:

4

Step-by-step explanation:

Answer 2

cosФ = 3/5

P.S. You can do this directly if you know cos53° = 3/5

Ф=53°

⇒tanФ = tan53° = 4/3

3tanФ = 4

Now if you don't know the above then,

cosФ = 3/5

sinФ = √(1-cos²Ф) = √(1-9/25) = 4/5

tanФ = 4/3

3tanФ = 4
