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: 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 degrees
