Answer:

y =  8 / (P + q + 4)

Step-by-step explanation:

Group ALL y terms on the left side:  Py + qy + 4y = 8.

Factor y out of the left side:              y(P + q + 4) = 8

Divide both sides by (P + q + 4):        y =  8 / (P + q + 4)

\bf Py+qy=-4y+8\implies Py+qy+4y=8\implies \stackrel{\textit{common factor}}{y(P+q+4)}=8 \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill y=\cfrac{8}{P+q+4}~\hfill

Sine we can figure out side XY by using Pythagorean Theorem (A^2+B^2=C^2) and find that XY= 5, We can use Soh Cah Toa (The ways I remember to use value charts) and we know that Cosine uses Adjacent over Hypotenuse in which therefore the answer would be 5/13
