Answer:

Part 1) 2 and 3

Part 2) C = 135

Step-by-step explanation:

Railroad:

2 and 3 because 1 is the transversal

Supplementary:

x - 50 + 19 = 180

Add 50 to both side

x + 19 = 230

Subtract 19 from both side

x = 211

Algebra:

C = ?

D = 45

Substitute x or C

x + 45 = 180

Subtract 45 from both side

x = 135

C = 135
