Nah. Pretty sure its geometry. ArkGoLucky are u sure u arent missing anything in the problem such as a 90 degrees angle?

There is a 90 degree angle where the 75 and 50 meet

\[
\sqrt{70^2+50^2}\cos(\theta) = 75

Do you see how I got this little nugget?

Actually, even better would be: \[
\tan(\theta) = \frac{50}{57}
\]

Then there is \[
\tan(\theta + 10.5^\circ) = \frac{50+x}{75}
\]

Okay all together, without errors \[
\begin{array}{rcl}
\tan(\theta) &=& \frac{50}{75} \\
\tan(\theta + 10.5^\circ) &=& \frac{50+x}{75}
\end{array}
\]

theta. I forgot that you could find an angle with two side lengths
