So, we use the pythagorean theorem again.

liamschumm · Answer

20^2 = 14^2 + x^2.

liamschumm · Answer

See, in a^2 + b^2 = c^2, 20 is c, since it is opposite the 90 degree angle, and a and b are 14 and x, respectively.

liamschumm · Answer

Do you know how to solve 20^2 = 14^2 + x^2?

anonymous · Answer

In this problem you would use the phtagreom therome (idk how to spell it srry) but because you got the hyptonuse you do it backwards so you would do 

$$20^{2}-14^{2}=204 $$
$$\sqrt{204} = 14.28 or 14.30$$

does that make sense?
