Oh wow, looks like a bit of algebra
anonymous

Nah. Pretty sure its geometry. ArkGoLucky are u sure u arent missing anything in the problem such as a 90 degrees angle?
anonymous
  • anonymous
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: \[ \tan(\theta) = \frac{50}{57} \]
anonymous
  • anonymous
Then there is \[ \tan(\theta + 10.5^\circ) = \frac{50+x}{75} \]
anonymous
  • anonymous
Okay all together, without errors \[ \begin{array}{rcl} \tan(\theta) &=& \frac{50}{75} \\ \tan(\theta + 10.5^\circ) &=& \frac{50+x}{75} \end{array} \]

What ever could have inspired you to solve it?

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