Find the exact value of:
Cos 52* cos 32* - sin 52* sin 32*

cos(84)

Step-by-step explanation:

cosAcosB - sinAsinB = cos(A+B)

cos(52)cos(32) - sin(52)sin(32)

= cos(52+32) = cos(84)

Or 0.1045

ian gonna lie that is way to much

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 %
