How to solve for sin, cos and tan on a right triangle:

SOHCAHTOA is helpful to memorise the equations for sin, cos and tan.

SOH is sin= opposite/hypotenuse

CAH is cos= adjasent/hypotenuse

TOA is tan= opposite/adjasent

the hypotenuse is found diagonal from the 90 degrees point, the adjacent side is found next to the angle point, and the opposite side is found across from the angle.

here are some examples of how to solve missing parts of a triangle:
