Two parallel lines are cut by a transversal and form a pair
Novosadov [1.4K]

Answer:

since alternate exterior angles are congruent, you get:  

6x + 5 = 7x - 4  

subtract 6x from both sides of this equation and add 4 to both sides of this equation to get 5 + 4 = 7x - 6x which results in 9 = x

 

solve for x to get x = 9 degrees.
