Question

Find the measure indicated in bold

(9x+1)

If you can please show how you got the answer. Thank you. ​

Answer 1

55

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
