Angle 2 is vertical to angle 1 which would make it EQUAL to angle 1 (angle 2 is 133 degrees) then you subtract 133 from 180 which will leave you with 47.
Y^2+4y=-8 add 8 both sides y^2+4y+8=0 in the form of ax²+bx+c=0 Factor it by formula -b+-(√b²-4ac)/2a -4+-(√16-32)/2*1 -4+-(√-16)/2 -4+-4i/2 -2+-2i where√-1=i
