Solution Steps
Step 1: Find the length of the opposite side.
Using the Pythagorean theorem ($a^2 + b^2 = c^2$), where $a$ and $b$ are the legs of the right triangle and $c$ is the hypotenuse, we can find the length of the side opposite to $\theta$. Let's call this side $x$. We are given that one leg is 4 and the hypotenuse is 7, so we have:
