Calculate cose to two decimal places.

Cosθ = -0.07

Step-by-step explanation:

Law of Cosines

c² = a² + b² - 2abCosC

The givens

a = 7, b = 8, c = 11, C = θ

Plug into the formula

11² = 7² + 8² - 2(7)(8)Cosθ

Square

121 = 49 + 64 - 112Cosθ

Combine terms

121 = 113 - 112Cosθ

Subtract 113 from both sides

8 = -112Cosθ

Divide both sides by -112

-0.07142857143 = Cosθ

Round to 2dp

Cosθ = -0.07

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
