**Solution**

RoyHi Madhubala,

Your answer seems to be an angle and not a trigonometric ratio. We need to find two trigonometric ratios: sin Θ and cos Θ.

See if there is a way we can express both left side and right side of the equation as 2 raised to (something). Then try and simplify

after that. Hope this helps!

RoyHi Chops_the_old,

Great work!

RoyHi Madhubala,

Great effort and you are getting very close now! Since theta is an acute angle, tan (theta) cannot be -3. Use this fact.

RoyHi Madhubala,

Great job!
