Final answer:
To find angle C, set up an equation using the given information and solve for x. Angle C is equal to the value of x obtained.
Step-by-step explanation:
To find angle C, we need to use the facts that angle A is congruent to angle D and angle B is congruent to angle E. From the given information, we can conclude that angle A is congruent to angle D, and angle B is congruent to angle E. Since angle F is equal to 2x - 30 and angle D is congruent to angle A, we have:
2x - 30 = 180 - (x + 2x - 30)
2x - 30 = 180 - 3x + 30
2x - 30 = 210 - 3x
5x = 240
x = 48
Therefore, angle C is equal to x, which is 48 degrees.
