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.

Out of 30 questions, Ahmad answer 12 of them incorrectly. What percent of the questions did he answer correctly?
kati45 [8]
First, you would need to determine how many questions he got correct. 
30 - 12 = 18

Next, you would need to create an equation for this problem. Let x represent the unknown percentage. 
\frac{18}{30} = \frac{x}{100}

Now, you would cross multiply. 
30x = 1,800

The last step would be to isolate the x. To do this, you would divide both sides of the equal sign by 30. 
x = 60

Ahmad got 60% of the questions correct. 

I hope this helps!
