Apair of parallel lines is cut by a transversal what is the measure of angle x

x=65°

Step-by-step explanation:

Here we are given a pair of parallel lines and a transversal line intersecting at two points.

We know that the alternate interior angles are equal to each other

please refer to the attached file. Here we see that D=J

and D=x+15

Hence x+15=80

subtracting 15 from both sides we get

x=80-15

x=65

Hence our answer is x=65°

sorry, i don't know i just need points, i'm new here. chao
