If you can separate the figures and the segment, or angle in question, is the same, the reflexive property of congruence can be used in the proof. ... Separating the two triangles, you can see Angle Z is the same angle for each triangle. Since they are the same angle, the angle is congruent to itself.
The answer is C. 1,000,000
40
8x5=40
10x4=40
Hope this helps
