In triangle ABC with the right angle at C, sin A=12. Which is the value of cos B [Hint: Draw the triangle!]

positive

step-by-step explanation:

the quadrant is facing upwards

the answer will be b x² +x-1

step-by-step explanation:

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 %
