Answer:
55
Step-by-step explanation:
First you'll need to know the corresponding angles
because of corresponding angles 9x+1 and -5+10x are vertical angles
the vertical angles theorem says the vertical angles are equal to each other. So, set both equations equal to each other
9x+1=-5+10x now isolate the x on one side
-9x -9x
1=-5+x
+5 +5
6=x now input x into the equation you are asked to fin
9(6)+1=55
