Right Triangle Hypotenuse and Height from Angle and Base

Enter one acute angle and the base to instantly get the hypotenuse, height, area, and trig ratios.

Input

Enter an acute angle in degrees and its adjacent base of a right triangle to find the hypotenuse and height.

Lengths use the same unit as the base you entered. Angles are shown in degrees.

How it works

  • With base (adjacent side) b and the entered acute angle theta, the height a is a = b times tan(theta).
  • The hypotenuse c is c = b divided by cos(theta), derived from cos = adjacent divided by hypotenuse.
  • The other acute angle is 90 degrees minus theta, the area is base times height divided by 2, and the perimeter is base plus height plus hypotenuse.
  • Enter an angle theta greater than 0 and less than 90 degrees, and a positive base.
  • sin, cos, and tan, along with their reciprocals csc, sec, and cot, are shown together.
