Answer:
102.73
Step-by-step explanation:
When the forces are at right angles, the resultant magnitude will be found as the hypotenuse of a right triangle with legs equal to the given forces. The Pythagorean theorem applies.
f = √(77² +68²) = √10553 ≈ 102.728
The magnitude of the resultant is about 102.73.
