2x3a=6a. 2x2b=4b. 2x-7=-14.
D. 6a+4b-14
Lines a and b are parallel, and line t is a transversal.
Notice that angles 2 and 7 are on the outside of the parallel lines, and they are on different sides of the transversal.
Angles 2 and 7 are alternate exterior angles.
The answer is (a) alternate exterior angles theorem.
It is by the "alternate exterior angles theorem" that angles 2 and 7 are congruent.
I believe the answer is =0.857
