Two parallel lines are cut by a transversal, as shown below. Solve for b. Then explain your reasoning.

b = 14

Step-by-step explanation:

Since both angles are diagonal each other, they are equal to each other.

5b = b + 56

-b      -b           (subtract b from both sides)

4b = 56

4       4            (divide both sides by 4 to solve for b)

 b = 14

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7
