Answer:

$x = - 23$

Step-by-step explanation:

$\frac{20 - (40 + x)}{12} \times 10 = 32.5 - 30 = 2.5$

$= > \frac{20 - (40 + x)}{12} = 0.25$

$= > \frac{20 - (40 + x)}{12} = \frac{1}{4}$

$= > 20 - (40 + x) = \frac{12}{4} = 3$

$= > 40 + x = 20 - 3 = 17$

$= > x = 17 - 40 = - 23$

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
