Me ive got 40 minutes to get this done. picture below

Is that the same picture twice?

Since X and Y are both midpoints by I think Thales' Theorem, one of the oldest in geometry, XY is parallel to VW.  So angles UYX and UWV are corresponding angles of a transversal, so are congruent and have the same measure.

m∠W = 40 deg

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,
