Question

15. a large totem pole in the state of Washington is 100 ft tall. At a particular time of day, the totem pole casts a 249-ft-long shadow. Find the measure of 12 years ago

Answer 1

tan A = 100/249

Answer 2

what do i do from there?

Answer 3

Answer 4

im so confused /:

Answer 5

i would say pythagerom theom

Answer 6

no nvm :P lemme see

Answer 7

first work out 100/249
- now you need to find the angle whose tangent is this value
use your calculator to do this (tan^-1)

Answer 8

We can use the tangent of A here %28side+opposite%29%2F%28side+adjacent%29
tan(A) = 100%2F249
tan(A) = .4016
Find the tan^-1; of .4016
A = 21.88 degrees
