if you mean a right triangle then the formula is a squared + b squared = c squared. a and b are the legs and c is the hypotunese. the legs are the smallest number then the hypotenese.
An example is a=3 , b= ? and c =5
use the formula : a squared + b squared = c squared
3 squared + b squared = 5 squared
9 + b squared = 25
-9 - 9
_________________________________________
b squared = 16
Then you have to take the squared root of 16 which is 4 and 4 is b squared.

A right triangle with a leg length of 48 inches and a hypotenuse of 80 inches has a third leg of: 64 inches.
-- Like every triangle, a right triangle has three interior angles.-- Unlike any other triangle, one of the angles in a right triangle is a right angle.The other two are both acute angles.-- One acute angle is the angle whose cosine is length of one leg / length of hypotenuse-- Other acute angle is the angle whose sine is length of the same leg / length of the hypotenuse-- The length of the hypotenuse is the square root of [ (length of one leg)2 + length of other leg)2 ]
A right triangle has a hypotenuse of length 10 and a leg of length 7 has an area of: 24.99 units2
If it's a right angle triangle then the other leg will also be 13 units in length and use Pythagoras' theorem if you need to find the length of the hypotenuse.
This is impossible. A leg cannot be greater than the hypotenuse. (Unless the triangle is part imaginary)
