The palmaris longus and the flexor carpi radialis muscles both attach on the humerus at the medial epicondyle. At a particular timepoint, the palmaris longus force vector is given in polar notation as $[56$ N$,329$ degrees$].$ The flexor carpi radialis force vector is given in polar notation as $[82$ N$,329$ degrees$].$ What is the magnitude of the force acting on the medial epicondyle due to these two muscle forces $($i$.$e$.$ what is the magnitude of the sum of these two vectors$)?$

Express your answer in Newtons to two decimal places. Do not include units in your answer.
