as an example make a right-angled triangle ABC with AB=5, BC=4 and AC=3
(notice 3^2 + 4^2 = 5^2)
relative to angle B, AC is the opposite, and BC is the adjacent, and AB is the hypotenuse.
the ratio AB/BC = opposite/adjacent is called the tangent of an angle.
in this case tangent B = 3/4 = .75
to get angle B depends on your calculuator.
I have a "Sharp" in front of me, and there is a 2ndF key at the top left
so to get my angle I press
and I get 36.87º
to get angle A, you simple take the difference between that angle and 90º, since angle C = 90
to find the tangent of the angle, press
you should get very close to .75,
(we won't get .75 itself, since we rounded off our previous result)
google 'trig ratios' and you should get the other two definitions
also look up SOHCAHTOA
