Step by Step:
(z^2 -2z)(10z-20)
z(z-2)+10(z-2)
(z+10)(z-2)
Hope this helps.

What are the missing measures bro?
Since the triangles are congruent the angles given are the same. If we know triangles have 180 degrees total within their angles then 44 + 55 - 180 = 81 degrees. Z=81
Answer:
42
Step-by-step explanation:
Line m and l are parallel so C and where that intersection is on the inside have the parallel lines, the angle there is an same side interior angle with C. Those add up to 180 degrees. So 180-82 is 98. Use vertical angle to find the angle in the triangle (not x yet; the other one). Vertical angles are congruent so that one is 98.
Now angles in a triangle add up to 180 degrees.
So we have 40+98=138.
The difference between 180 and 138 is 180-138=42 (that is x)
