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.

it's 100

step-by-step explanation:

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

  n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the  14th  row will have 100 seats

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100
