∠1 and ∠2 are alternate exterior angles where transversal BE crosses parallel lines AC and DF, therefore they are equal. ∠2 and ∠3 are opposite angles of a parallelogram, therefore they are equal.

... ∠1 = ∠2

... 3x -5 = 2x +15 . . . . substitute the given values

... x = 20 . . . . . . . . . . . add 5-2x

The measures of angles 1, 2, and 3 are 2·20+15 = 55 . . . degrees.

In a parallogram the two angles on the same side ( Angle T and Angle C) equal 180 degrees

So we have 8x +29 + 2x +11 = 180

combine the like terms:
10x + 40 = 180

Subtract 40 from each side:
10x = 140

Divide each side by 10:
X = 140 /10
X = 14

Now we have X, replace X into the equation for angle C

2(14) +11 = 28 + 11 = 39 degrees
