# Get legs length from right angle and hypotenuse

Here I have a 2 points. $A$ (lat,lng) and $B$ (lat,lng), this two point is hypotenuse of right triangle.

How I can get legs length if I know angle, hypotenuse and these points?

-

Make equations like:

1) $$\frac{\sin(\text{angle})}{\sin(90^{\circ}-\text{angle})} = \frac{\text{firstLeg}}{\text{secondLeg}}$$

2) $$\text{firstLeg}^2 + \text{secondLeg}^2 = \text{hypotenuse}^2$$

I dont know angle, I just know that I have right angle triangle and hypotenuse –  adria Aug 5 '13 at 10:41
so then it could be an infinite number of different triangles :) unless you have some more information, like the legs are both the same length or something... –  Gintas K Aug 5 '13 at 10:46
yes I have First point(lat,lng) and Second point(lat,lng) –  adria Aug 5 '13 at 13:00
as I understood it's the end points of a hypotenuse? –  Gintas K Aug 5 '13 at 13:14
yes but every point have latitude and longitude –  adria Aug 5 '13 at 14:05
