Pleasee help meee!! From the top A of a building 125m above the street ,the angle of elevation of the top of B of a second building on the opposite side is 18°36' and the angle of depression of the base of the second building from A is 39°48'
(a). Calculate the width of the street.
(b). Calculate the height of the wall on the opposite side
(c). A taut extension string connects points A and B. A bird spots an insect sitting at a point X on the string. X is three quarter way from A The birds landing at X causes vertical sag of 50cm on X. Calculate the angle of depression of X fro. B after the sag.​

the answer   is 200

step-by-step explanation:

this is a problem about poisson probabilities.   i don't know if you've

already studied poisson distributions, or if you have a place to look

to read more about the subject.  

here's how you can see a poisson distribution coming.   when there are

a lot of events that may happen at any time (or any place), and when

you're counting how many of them happen at a particular time (or a

particular place), and each event is independent of the others, then

the result is a poisson distribution.   this is roughly true for the

chocolate chips; one chip being in a cookie has only a small effect on

the probability that another chip will be in the cookie.

once you know you have a poisson distribution, you know a lot.   there

is only one parameter to a poisson distribution, so if you know the

mean, you know everything.   the form of the distribution is

  probability of n chips = {[e^(-x)]*(x^n)} / (n! )

it would more likely be bald eagle because its has more in the box so about 75%.
