Legs 3 and 4, hypotenuse 5, angles 36.8699° and 53.1301°.

  • Solved from Two legs (a, b). The two acute angles sum to 90°.
  • The hypotenuse 5 is the longest side (opposite the right angle). The altitude from the right angle to the hypotenuse is 2.4 units.
  • The sides 3-4-5 form a Pythagorean triple: all three are whole numbers satisfying a² + b² = c².

Next stepSwitch the "What you know" mode to re-solve from a different pair, or toggle angle units between degrees and radians.
