Question

What is the value of x?

Answer 1

x = 70

Explanation:

The two angles shown are same side interior angles and same side interior angles add to 180 when the lines are parallel

45+ 2x-5 = 180

Combine like terms

2x+40 = 180

Subtract 40 from each side

2x+40-40 = 180-40

2x= 140

Divide by 2

2x/2 = 140/2

x = 70

Answer 2

x=70

Explanation:

45+2x-5=180

40+2x=180

2x=140

x=70
