What is the rate of change ?
postnew [5]
The rate of change is also called the slope
 the formula foe the rate of change is (y2-y1) / (x2-x1)

x1 = -3
x2 = 6
y1 = 14
y2 = -1
 rate of change = (-1 - 14) / (6- (-3)
= -15 / 9
= -5/3

PSYCHO15rus [73]

Answer and Step-by-step explanation:

90ft = a

55ft = b

50ft = c

Plug into equation.

50^{2}  = 90^{2}  + 55^{2}  - 2(90)(55)cosC\\\\2500 = 11125 - 9900(cosC)\\\\-8625 = -9900(cosC)\\\\0.8712 = cosC\\\\cos^{-1} (0.8712) = C\\\\29.4

29.4° is the answer.
