Question

To solve the equation 3 sin(2x) = 5cosx, you should rewrite it as
O A. cosx(3sinx - 5) = 0
0 B. cosx(6sinx - 5) = 0
O C. 3sinx + 5cosx = 0


Help me out

Answer 1

Answer:

OPTION B

Step-by-step explanation:

3sin(2x)=5cos(x)

3×(2sinxcosx)=5cos(x)

6sin(x)cos(x)=5cos(x)

6sin(x)cos(x)-5cos(x)=0 Factor out a cos(x)

cosx(6sinx-5)=0
