A large totem pole in the state of Washington is 100ft tall. At a particular time of day, the totem pole casts a 249ft-long shadow. Find the measure of <A to the nearest degree.

Can someone please explain

You don't say where angle A is, I will assume at the end of the shadow.

simple case of
tanA = 100/249
A = tan^-1 (100/249) = .....

you do the button-pushing
