Answer:

x=91

Step-by-step explanation:

Since these angles are same side exterior angles, they will add to 180 degrees. Therefore:

(x-3)+(x+5)=180

Drop the parentheses.

x-3+x+5

Combine like terms.

2x+2=180

Subtract 2 from both sides.

2x=178

Divide both sides by 2.

x=89

Answer:

x=89

Step-by-step explanation:

Okay so. because of the rules of parallel lines and their intersecting lines, we know that the upper angle and the lower angle are complimentary angles. This means that they add up to equal 180 degrees.

Because of this, we know that (x-3)+(x+5)=180

2x+2=180

2x=178

x=89
