Can someone walk me through this?

So you can set up proportion.

$\dfrac{7.5\ \text m}{76^\circ} = \dfrac C{360^\circ}$

Here, you need to solve for C.

You can do that by multiple both sides by 360 and then you should get $360^\circ\cdot\dfrac{7.5\ \text m}{76^\circ} = C \approx \boxed{35.526\ \text m}$

Hope this helps.
