Two parallel lines are crossed by a transversal. What is the value of k ?
MakcuM [25]

Answer:

k= 60

Step-by-step explanation:

The angles are alternate exterior angles and alternate exterior angles are equal when the lines are parallel.

2k+11 = 131

Subtract 11 from each side

2k+11-11 =131-11

2k =120

Divide by 2

2k/2 =120/2

k = 60
