Sines Calculator

Input

$$Alpha=105$$ $$Side A=7$$ $$Beta=35$$

The Law of Sines Solution

Law of Sines: \({a\over sin A} = {b\over sin B} = {c\over sin C}\)
Put in the values we know: \({a\over sin A} = {7\over sin(35°)} = {c\over sin(105°)}\)
Ignore \(a\over sin A\) (not useful to us): \({7\over sin(35°)} = {c\over sin(105°)}\)
Now we use our algebra skills to rearrange and solve:
Swap sides: \({c\over sin(105°)} = {7\over sin(35°)}\)
Multiply both sides by \(sin(105°)\): \(c = ({ 7\over sin(35°) }) × sin(105°)\)
Calculate: \(c = ( {7\over 0.574... }) × 0.966...\)
\( c = 11.8 \)

what is Sines?

The law of sines states that the proportion between the length of a side of a triangle to the sine of the opposite angle is equal for each side:

a / sin(α) = b / sin(β) = c / sin(γ)

This ratio is also equal to the diameter of the triangle's circumcircle (circle circumscribed on this triangle).

Note that you can use this law for any triangle, also for one that isn't a right triangle.

Law of sines application

You can transform the law of sines formulas to solve some problems of triangulation (solving a triangle). You can use them to find:

  1. The remaining sides of a triangle, knowing two angles and one side.
  2. The third side of a triangle, knowing two sides and one of the non-enclosed angles. In some cases (ambiguous cases) there may be two solutions to the same triangle. If the following conditions are fulfilled, your triangle may be an ambiguous case:
  • You only know the angle α and sides a and c;
  • Angle α is acute (α < 90°);
  • a is shorter than c (a < c);
  • a is longer than the altitude h from angle β, where h = c * sin(α) (a > c * sin(α)).

You can also combine these equations with the law of cosines to solve all other problems involving triangles.
