how do i work out the length of the adjacent if i know the hypotenuse and the other one i forgot
+9466 If you know the length of the hypotenuse and the length of a leg ,
you can use the Pythagorean theorem:
(leg)2 + (other leg)2 = (hypotenuse)2
If you know the length of the hypotenuse and the measure of an angle (other than the 90º angle) ,
you can find the length of the leg adjacent to that angle using this:
cos (angle) = (length of side adjacent to the angle) / (hypotenuse)
