Answer:

x = 59°

Step-by-step explanation:

The angle marked 115° and the angle that is the sum of angles x and 56° are alternate interior angles, so have the same measure:

115° = x +56°

59° = x . . . . . . . subtract 56°

Answer:

x = 59

Step-by-step explanation:

angle 115 and angle 56 + x are alternate angles and congruent, thus

56 + x = 115 ( subtract 56 from both sides )

x = 59

Answer:

Not a solution.

Step-by-step explanation:

y = 5x + 9

-3 = 5(-2) + 9

-3 = -10 + 9

-3 ≠ -1

The point given is not on the line. It is NOT a solution to the equation.

Hope this helps.
