Answer 2

If

tan

(

θ

)

=

4

then the ratio of the opposite side to the adjacent side is

4

:

1

Two possibilities exist depending upon whether

θ

is in Quadrant I or Quandrant III; as indicated below:

In either case the relative length of the hypotenuse is given by the Pythagorean Theorem as

Since

for this case
