My triangle solver says EF ≈ 7.5 ft.
_____
The law of cosines is usually used for this.
EF^2 = DE^2 +DF^2 -2*DE*DF*cos(D)
.. = 6^2 +11^2 -2*6*11*cos(40°)
.. ≈ 55.88
EF ≈ √55.88 ≈ 7.5 . . . ft
Answer:
slope of the graph is

Step-by-step explanation:
slope of a graph = (y2 - y1) / (x2 - y1)
- 1 - (-3) / ( -24 - ( -8 ) )
- 1 + 3 / -24 + 8
- 4 / -16
- 1 / -4
- -1 / 4
hence the slope of the graph is
