x=11
Step-by-step explanation:
Due to angles DCA and CAB being Alternate Interior Angles, we know that they will be equal. This means that
°
Next, we can find the measure of the angle DCE.
Angles BCE and BCA are supplementary. This means that they will add together to be 180°
This means that 180-BCE=BCA
Which means
As all of the angles in a triangle must add together to be 180 degrees, we can set up the following equation
