=810ft+[540ft+2(1/2x5x6.75)ft]

Find what y equals please (geometry) :)

Answer: y=31.97°

Explanation: We can use trig ratios to find y and they are SohCahToa.

We can use Sin y, because when y is the reference angle, the 9 cm side is the opposite and the 17cm is always the hypotenuse.

We must take the inverse of Sin (9/17) to get about 31.9657, which we can round to 31.97°.
