Important Formula:
Sin(q) = Opposite / Hypotenuse
Cos(q) = Adjacent / Hypotenuse
Tan(q) = Opposite / Adjacent
Select what (angle / sides) you want to calculate, then enter the values in the respective rows and click calculate.
If you want to calculate hypotenuse enter the values for other sides and angle.

The formulae (formula) for finding angle and sides of triangle can be easily remembered using the sentence - "Old Harry And His Old Aunt"

Sin (q) = Old/Harry = Opposite/Hypotenuse
Cos (q) = And/His = Adjacent/Hypotenuse
Tan (q) = Old/Aunt = Opposite/Adjacent
