decide whether the triangles are similar. if so, determine the appropriate expression to solve for x.

the triangles are not similar; no expression for x can be found.
δabc ~ δdef; x equals r times w over u
δabc ~ δefd; x equals r times w over z
δabc ~ δfde; x equals z times w over r

]supplementary angles are two angles that add up to . • complementary angles are two angles that add up to degrees. • adjacent angles share a and a • congruent angles have the measure. • an triangle has one angle that is greater than 90 degrees. • a triangle with angles 45°, 45°, and 90° would be a triangle
