Answer:
B.
Step-by-step explanation:
Since 3.74 is rounded to the hundredths place, it is not the ideal exact solution for m^2 = 14.
To solve for m you would have to square root m and 14, which gives you . This is the best answer for the problem.
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
