Find the missing angles in the parallelogram

On the first pass, you know ...

Then on the second pass, you can figure ...

And the remaining angles can be determined using external angle and sum-of-angle relationships.

55/i dont know i do it for the points

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 %
