Answer:
y =7.642881742
Step-by-step explanation:
tan A = opp side/adjacent side
tan 63 = 15/y
y tan 63 = 15
y = 15/ tan 63
y =7.642881742
Move all to one side, make other side zero, and I like x^2 term to be positive
5-11x^2=-8x
add -5+11x^2 to both sides
0=11x^2-8x-5
4+3x=-x^2+2
add x^2-2 to both sides
x^2+3x+4+2=0
x^2+3x+6=0
x(x+2)=-5
add 5 to both sides
x(x+2)+5=0
x^2+2x+5=0
(2x-1)^2=1
expand
(2x-1)(2x-1)=1
4x^2-2x-2x+1=1
minus 1 from both sides
4x^2-4x=0
