plzz help to solve this​

Answer 1

Answer:

I am just showing you basic step. Then you can solve it easily.

Step-by-step explanation:

√3 sin theta = cos theta

or , tan theta = 1/√3

or, theta = 30°

Now just put 30° in place of theta and calculate the value

Answer 2

Answer:

sin Φ/cos Φ=√3

tan Φ=√3

Φ=60°

3cos²Φ+2cosΦ/3cosΦ+2

cosΦ(3cosΦ+2)/3cosΦ+2

cosΦ

cos60°

1/2
