Answer:

B = 48

Step-by-step explanation:

You are given that the two vertical lines are parallel. That means that the alternate interior angles are  equal (they form a Z shape).

So the given is that A = B

A = 5x - 12

B = 2x + 24

Solution

5x - 12 = 2x + 24

5x - 12 = 2x + 24 + 12

5x = 2x + 36

5x - 2x = 36

3x = 36

x = 36/3

x = 12

================

B is

B = 2x + 24

B = 2*12 + 24

B = 24 + 24

B = 48
