The thing about that problem is that when the circle is inscribed inside that triangle, the side measures created are doubled. By that I mean that the 9 on the top right is also the measure of the top left. Same thing for the 13 and the 16. The lower left unmarked side length is 13, the lower right side length is 16. Now add it all up: 9+9+13+13+16+16
X + 2 is an absolute value, so -5 becomes 5
5 + 2 = 7
-4 x 7 = -28
The answer is A. -28
Answer:

</u></h2>
Step-by-step explanation:
Using Pythagoras Theorem:

The two posts are parallel lines. The ground is a transversal.
The angles measuring 4x and 75 are same side interior angles, so they are supplementary. Their measures add up to 180.
4x + 75 = 180
4x = 105
x = 26.25
