Amount of points don't matter what is the question lets see if I can help
We'll use the Law of Cosines
We'll call
side a = length 5
side b = length 8
side c = length 10
and their corresponding angles as A, B and C
"C" would be the largest angle
cos (C) = (a^2 + b^2 - c^2) / 2 * a * b
cos (C) = (5^2 + 8^2 - 10^2) / 2 * 5 * 8
cos (C) = 25 + 64 -100 / 80
cos (C) = -11 / 80
cos (C) =

The largest angle is 97.903 Degrees
Answer:
(0, 1)
(4, 17)
Step-by-step explanation:
2x^2 - 4x + 1 = 4x + 1
2x^2 - 8x = 0
x(2x - 8) = 0
therefore either
x = 0
or
2x - 8 = 0
2x = 8
x = 4

Answer:
3 hours
Step-by-step explanation:
290.28-200.22=90.06
90.06/30.02=3
