Question

If 2 sinA = 3 cosA then the value of cosA is​

Answer 1

Given:-

• 2 sin A = 3 cos A

Solution:-

Case 1:

(sinA)^2 + 0^2 = 1

sinA = 1

Case 2:

(sinA)^2 +(4/5)^2 = 1

(sinA)^2 + (16/25) =1

(sinA)^2 = 1 - (16/25)

(sinA)^2 = 9/25

sinA = 3/5

Answer 2

Answer:

cosA=2 sinA/3 is your answer and maybe this question is incorrect please check.
