The value of x in the trapezoid is 11.
<h3>Properties of an isosceles trapezoid</h3>
- The base angles are the same
- The sum of opposite angles is 180° or supplementary.
- The diagonals are the same in length.
Therefore, the angle 9x and 7x + 4 are supplementary.
Hence,
9x + 7x + 4 = 180
16x + 4 = 180
16x = 180 - 4
16x = 176
x = 176 / 16
x = 11

Answer:
5.25 miles.
Step-by-step explanation:
What I did was I took 3/4 and made it into its decimal form which is 3/4. I then times it by 7 to get 5.25.
5.25 miles is your answer.
3+3+3+4+4+5+6+6+7+9+9=59
59/11=5.36
so your mean is 5.36
X can be 1, 2, 3, 4
R can be 6, 4, 2, 0
-1, -4 because 2+3(-1)= -1 and 4+8(-1)= -4
