For questions 13-15, find X so that 9 ||
13. X=
14. X=
15. X=
PLEASEE

Step-by-step explanation:

13. The given angles are alternate interior angles, so these angles are congruent. Make an equation in which they are equal to each other and solve for x:

14. The given angles are same-side interior angles, so they are supplementary. Make an equation in which the sum of the angles is equal to 180° and solve for x:

15. If you remove the horizontal line, the given angles are corresponding angles. These are congruent. However, make sure to add back the horizontal transversal line. Since this creates a 90°, add this to the given angle value:

Now set this value equal to the other angle and solve for x:

:Done

not sure but it may be b, as i said i'm not sure.
