Given the hypotenuse and the base ...
-- divide the (base) by the (hypotenuse); get a number less than '1'.
-- the number is the 'cosine' of the elevation angle.
-- either take the cos-1 of the number on a calculator, which is the angle
OR
-- look up the number in a table of cosines and see what angle it represents.

It is: perimeter minus hypotenus+base = height Area = 0.5*base*height
The side of a triangle that is opposite to 90 degree angle is called hypotenuse. The side that is opposite to the given angle (The angle that is under calculations) is called opposite. The side that is adjacent with the given angle is called base.
The answer depends on whether the base is one of the legs of the right angle or the hypotenuse. Also, a triangle cannot have a diagonal.
the sides can be found out by using trignometry.. sines and cosines.. sine of an agle is perpendicular/hypotenuse cosine of an angle is base/hypotenuse..
Use trigonometry if another angle is given. Use Pythagoras' theorem if the hypotenuse is given. Multiply the area by 2 and divide it by its height if the area is given. Or simply measure it.
