Can someone explain this?
the answer is d, but i want to know how you get it.

Using the law of sines:

Sin(angle) = Opposite leg / hypotenuse (A to C)

Sin(63 degrees) = 15 ft / A to C

A to C = 15 / sin(63)

A to C = 15 * cosec 63 degrees.

The answer is D

factor trees are nice.

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 %
