First, Look at the attached picture as a reference.
Now, using Pythagoras theorem,
![AC^2=AB^2+BC^2 \\\\AC=\sqrt{AB^2+BC^2 }\\\\AC=\sqrt{10^2+(10\sqrt3)^2}\\\\ AC = \sqrt{100+300}\\\\AC=\sqrt{400}\\\\AC=20~in.](https://tex.z-dn.net/?f=AC%5E2%3DAB%5E2%2BBC%5E2%20%5C%5C%5C%5CAC%3D%5Csqrt%7BAB%5E2%2BBC%5E2%20%7D%5C%5C%5C%5CAC%3D%5Csqrt%7B10%5E2%2B%2810%5Csqrt3%29%5E2%7D%5C%5C%5C%5C%20AC%20%3D%20%5Csqrt%7B100%2B300%7D%5C%5C%5C%5CAC%3D%5Csqrt%7B400%7D%5C%5C%5C%5CAC%3D20~in.)
Now, lets find the elevation of the sun.

![tan\theta = \frac{AB}{BC} \\\\ tan\theta = \frac{10}{10\sqrt3} \\\\ \theta = tan^{-1} \left(\frac{10}{10\sqrt3}\right) \\\\ \boxed{\theta = 30 \°}](https://tex.z-dn.net/?f=tan%5Ctheta%20%3D%20%20%5Cfrac%7BAB%7D%7BBC%7D%20%5C%5C%5C%5C%20tan%5Ctheta%20%3D%20%20%5Cfrac%7B10%7D%7B10%5Csqrt3%7D%20%5C%5C%5C%5C%20%5Ctheta%20%3D%20tan%5E%7B-1%7D%20%5Cleft%28%5Cfrac%7B10%7D%7B10%5Csqrt3%7D%5Cright%29%20%5C%5C%5C%5C%20%5Cboxed%7B%5Ctheta%20%3D%2030%20%20%5C%C2%B0%7D)
∴ The elevation of the sun is 30°
42.50 is the answer because you have to add them and then divide the answer by 3
