Answer:
75°
Step-by-step explanation:
In a parallelogram, any two adjacent angles are supplementary. In other words, they total 180.
Angle D and Angle E are adjacent. Thus, they are supplementary. In other words:
Substitute them for the equations:
Combine like terms and add on the left:
Subtract 36 from both sides:
Divide both sides by 12:
Thus, the value of x is 12.
Note that Angle D and Angle C are also adjacent. Thus, their angles also equal 180.
So:
Substitute the equation for D:
Plug in 12 for x:
Simplify:
Subtract 105 from both sides:
Thus, Angle C is 75 degrees.
