I NEED HELP ASAP!!! PLEASE HELP ME!!!​
mars1129 [50]

Answer:

X = 75

Step-by-step explanation:

Angle F and angle X are corresponding angles so they are congruent  (equal)

Angle F and 105 form a straight line so they are supplementary angles, which means they add to 180

F+ 105 = 180

F = 180-105

F = 75

F = X = 75
