Question

What is x and the Theorem? Someone please help asap!

Answer 1

Answer:

x = 75

Step-by-step explanation:

Corresponding angles on the same side of the transversal are equal

10x + 5 = 12x - 9                    Add 9 to both sides

10x + 5 + 9 = 12x                   Combine

10x + 14 = 12x                         Subtract 10x from both sides

14 = 12x - 10x                         Combine

14 = 2x                                    Divide by 2

2x = 14

x = 14/2

x = 7

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

10x + 5 = 10*7 +  5

10x + 5 = 75

12x - 9 = 12*7 - 9

12x - 9 = 84 - 9

12x - 9 = 75
