Answer:
C
Step-by-step explanation:
the lines are intersecting at 1,3
The equation would be X +21+ 2X +17+ 2X +17 equals 180 when solved you get X equals 25
I got 45 for x and 135 for z.
X and 3x are supplementary (they equal 180) x+3x=180 — 45+3(45)=180
Then x and z are also supplementary x+z=180 — 45+z=180
(45-45)+z=180-45
Z=135
Sorry if this is wrong. I did my best, hope it helps
