What value of x is in the solution set of 9(27 + 1) < 94 - 18?

If angle ywz = 17, what is angle wxy? ok so i'm confused on this because the triangles are congruent so that means they have the same measurement which would make wxy=17, but don't all triangles have total measures of 180 degress? ?me.

Which expression is equivalent to (9x - 3 1/ + 1 3/8)
