Find the value of x that makes p||q
padilas [110]

Answer:

1. x = 30

2. x = 39

Step-by-step explanation:

1.

4x and ( 3x + 30 ) are alternate exterior angles,

Alternate exterior angles are equal.

4x = 3x + 30

4x - 3x = 30

x = 30

2.

x and ( 3x + 24 ) are co - interior angles.

Sum of co - interior angles is 180,

x + 3x + 24 = 180

4x + 24 = 180

4x = 180 - 24

4x = 156

x = 156 / 4

x = 39
