What is the measure of ∠f, to the nearest degree? 44° 57° 71° 78°

Option A. 44°

Step-by-step explanation:

In a given triangle FGH sides have been given as FG = 7 yards, FH = 6 yards, and GH = 5 yards.

We have to calculate the approximate value of ∠F.

We apply the cosine rule in the given triangle.

5² = 7² + 6² - 2×7×6×cosF

25 = 49 + 36 - 84× cosF

25 = 85 - 84 cosF

84cosF = 85 - 25 = 60

F = 44°

Therefore option A. 44° is the correct answer.

the reason why your question keeps getting deleted because this is not a school related question : )

i will answer your question though.

i never tried church's

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
