Question

Parallel lines e and f are cut by transversal b. What is the value of y?

Answer 1

Answer:

y = 130

Step-by-step explanation:

Those two exterior angles are equal (property of parallel lines)

y is thsupplement of 4x - 14

2x + 18 = 4x - 14                     Add 14 to both sides

2x + 18 + 14 = 4x - 14 + 14      Combine like terms

2x + 32 = 4x                           Subtract 2x from both sides

2x-2x+32=42-2x                    Combine

32 = 2x                                   Divide by 2

32/2 = x

16 = x

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

4x - 14 =64 - 14 = 50

y = 180 - 50

y = 130
