In the above right triangle the sides that make and angle of 90° are a and b, and h is the hypotenuse These calculators may be used to check your answers to questions that you have solved analytically Formulas Used in the Different Calculators The Pythagorean theorem used in the above triangle gives a 2 b 2 = h 2 a = √ (h 2 b 2) bYou can use the tangent function to find the adjacent leg All that remains to know the length ratios for the sides of the triangle is to determine the length of EC, its hypotenuse, via the Pythagorean Theorem The square of length EC must equal the square of 1 plus the square of (2 – √3), so EC, squared, equals 1 4 – 4√3 3, or 8 – 4√3 The hypotenuse (EC) must therefore be the
