the angle of elevation to the sun is 24°. what is the length of the shadow cast by a person 1.82 m tall?​
laiz [17]

Answer:

4.089

Step-by-step explanation:

24 degree is the Angle of elevation. SO we can use in this triangle Tan.

So tan 24 = AB/BC because tan is the ratio of height over adjacent.

So we can say it is tan 24 = (1.82)/BC

So BC = (1.82)/tan(24) = 4.089m

BC is representing shadow of men. So shadow of men is 4.089m

If you have lived for a million seconds, how many birthdays have you had?
Romashka [77]

A million seconds is not that long.  My next birthday is in  1,296,000  seconds
from now, and I have already lived more than  2.3 billion seconds !

(1,000,000 seconds) x (1 day / 86,400 seconds) =

                 11days 13hours 46minutes 40seconds .

It's possible that you might have one birthday within that length of time,
but it's not guaranteed.  It would have to be the RIGHT million seconds.

If that's been your whole life so far ... you are 1 million seconds old ..,
then you have not had your first birthday yet.
