A right triangle has a hypotenuse of length 2.00 m, and one of its angles is 28.0°. What are the lengths of the following sides?
(a) the side opposite the 28.0° angle
________ m
(b) the side adjacent to the 28.0° angle
________ m
What formula should I use to solve this problem? Thank you
Update:Thank you !

Verified answer
sin(28.0) = (opposite side)/(2.00)
cos(28.0) = (adjacent side)/(2.00)
make sure your calculator's in degree mode...
SOHCAHTOA
a) sin(28) * 2 SOH = sine is opposite over hypotenuse
b) cos(28) * 2 CAH = cosine is adjacent over hypotenuse
