To solve this problem, you set up the equation 45+(2x-5)=180

Next, subtract 45 from 180 to get the equation 2x-5=135

After that, add 5 to 135 to get 2x=140

Diviode 140 by 2 to get X=70

Answer:

x=70

Explanation:

45 degree and 2x-5 are inside the parallel lines

45 abd 2x-5 are consecutive interior angles

Two consecutive interior angles are supplementary

So the sum of two angle are equal to 180 degree


45+2x-5= 180

Combine like terms


40+2x= 180

Subtract 40 from both sides


2x= 140

Divide both sides by 2


x=70
