Question

sin theta-√3 cos theta=0 find theta​

Answer 1

Answer:

theta=60°

Step-by-step explanation:

sin theta-√3 cos theta=0

sin theta=√3cos theta

sin²theta=3cos²theta---------(squaring)

sin²theta-3cos²theta=0

1-cos²theta-3cos²theta=0

1-4cos²theta=0

-4cos²theta=-1

4cos²theta=1

cos²theta=1/4

cos theta=1/2.............(taking square roots)

so, theta=60°
