I'm stuck on this question. I believe it's 42.7 but I'm not sure, correct me if I am wrong. Please include how you found the answer, thank you!

Note that we  have an adjacent side to the 31°  angle...and we are looking for the opposite side

 

So...the tangent seems the natural choice, here....so...

 

tan (31°)  = x  / 22         multiply both sides by 22

 

22 *  tan (31°)  =  ≈  13.2  ft

 

 

cool cool cool
