First, let's draw the free body diagram:
The equation used to find the resulting force Fr is the Pythagorean Theorem:

Using the given values, where the hypotenuse is the resulting force Fr, we have:

Now, solving the equation, we have:
![\begin{gathered} F^2_r=4225+2025 \\ F^2_r=^{}6250 \\ F_r=\sqrt[]{6250} \\ F_r=79.06\text{ N} \end{gathered}](https://img.qammunity.org/2023/formulas/physics/college/1cf18cyr84m66b9k8p6pqi7kyr484qtbjl.png)
Therefore the resulting force is 79.06 N.
