When we use a protractor to measure the angle, we should measure an angle that is close to the calculated value $78.7^{\circ}$
We can calculate the angle $x$ as follows: $tan~x = \frac{opp}{adj}$ $tan~x = \frac{250}{50}$ $tan~x = 5$ $x = tan^{-1}~(5)$ $x = 78.7^{\circ}$ When we use a protractor to measure the angle, we should measure an angle that is close to the calculated value $78.7^{\circ}$
