Find x, then find the measurement of both angles.

A: x = 20; both angles measure 112 degrees
B: x = 20; both angles measure 110 degrees
C: x = 30; both angles measure 114 degrees
D: x = 30; both angles measure 118 degrees.

C:x=30:both angles measure 114 degrees

Step-by-step explanation:

in 2 parallel lines with a transversal, the marked angles are alternate exterior angles, which means that both angles are congruent(equal)

ur equation is: 2x+54=4x-6

60=2x

x=30

we have now eliminated options a and b

CHECK:

2*30+54=60+54=114

4*30-6=120-6=114

114=114

PLEASE MARK BRAINLIEST

Start at zero on your number line.
To add 15 floors, we count up to 15. (0+15=15)
Then we go down 9 floors...count 9 down and you'll get to 6. (15-9=6)
Then we go up 11 floors...count up 11 and you'll get to 17. (6+11=17)
Then down 19 floors...count down 19 and you end up at -2.  (17-19=-2)
The net change is 2 floors down.
