Sagot :

Answer:  B) 35 degrees

Explanation:

Angles 4 and 8 are corresponding angles since they are both in the southwest corner of their respective 4 corner configuration.

Corresponding angles are congruent when we have parallel lines like this.

Set the expressions equal to each other and solve for x

angle 4 = angle 8

x+20 = 2x+5

x-2x = 5-20

-x = -15

x = 15

Use this x value to find the two angles to help confirm we have the correct x value, and to finish up to answer the question.

  • angle 4 = x+20 = 15+20 = 35
  • angle 8 = 2x+5 = 2(15)+5 = 30+5 = 35

So that's why the answer is B) 35 degrees
