Answer:
102 degrees.
Step-By-Step Explanation:
We know that D is x and E is 1/2x and Angle F is 2 less than angle D.
So if we use the sum of 180 and solve for x, we will find angle D.
This is the equation: x+.5x+2x-2=180
solve: Â Â Â Â Â Â Â 3.5x -2 = 180
               +2   +2
              3.5x=182
              /3.5x  /3.5x
                X = 52
2(52)-2 = 102 degrees
Thus the answer is 102 Â degrees
