< = Angle
<R and <S are complementary angles, and <U and <V are also complementary angles. If m<R=y2, m<S=2x+3, m<U=2xy, and m<V=x1, find the values of x, y, m<R, m<S, m<U, and m<V

y2 + 2x+3 = 90
2x + y = 89
2xy + x1 = 90
3x  y = 91
add the two equations
5x = 180
x = 36
take it from there,
sub x=36 into one of the equations above to find y, then evaluate each of the angles
