I don't know what the exact problem is but I can give you a tips:

Use Pythagoras theorem and special angles table!!

Pythagoras theorem: The square of the longest side in a right angled triangle is equal to the sum of squares of the other 2 sides.

OR

$a^2 + b^2 = c^2$

Special angles table:

f(x)\^x	30 degrees/ 1/6 pi radians	45 degrees/ 1/4 pi radians	60 degrees/ 1/3 pi radians
sin x	$\dfrac{1}{2}$	$\dfrac{1}{\sqrt2}$	$\dfrac{\sqrt3}{2}$
cos x	$\dfrac{\sqrt3}{2}$	$\dfrac{1}{\sqrt2}$	$\dfrac{1}{2}$
tan x	$\dfrac{1}{\sqrt3}$	$1$	$\sqrt 3$
