The first step in using the Obtuse Triangle Calculator is to input the known values. This can include any two sides and the angle opposite one of the sides or any one side and the two angles adjacent to it. For example, if you know the lengths of sides a and b and the angle opposite side a, you would input "a=3, b=4, A=100" into the calculator.
The Obtuse Triangle Calculator uses the law of cosines and the law of sines to calculate the missing values of the triangle. The law of cosines states that:
The law of sines states that:
By using these formulas and the known values of the triangle, the Obtuse Triangle Calculator can calculate the missing side or angle. For example, if you input "a=3, b=4, A=100" into the calculator, it would calculate that the length of side c is approximately 6.37 units.
The Obtuse Triangle Calculator is a helpful tool for quickly and easily finding the missing side or angle of an obtuse triangle. By following the steps outlined in this tutorial and using the laws of cosines and sines, you can quickly calculate the missing values of any obtuse triangle. This can be useful in a variety of applications, from engineering to architecture to mathematics.
