Web14 dec. 2024 · Solve for the area of the triangle. To find the area of a triangle you need two side lengths which you have now obtained. One equation for the area of a triangle is. \text {area} = \frac {1} {2} × b × c × \sin (A) area = 21 × b× c× sin(A) The " b " and " c " represent two sides and A is the angle between them. Therefore: WebUnfortunately, while the Law of Sines enables us to address many non-right triangle cases, it does not help us with triangles where the known angle is between two known sides, a SAS (side-angle-side) triangle, or when all three sides are known, but no angles are known, a SSS (side-side-side) triangle.In this section, we will investigate another tool for solving …

It took quite a few steps, so it is easier to use the "direct" formula (which is just a rearrangement of the c 2 = a 2 + b 2 − 2ab cos(C) formula). It can be in either of these forms: cos(C) = a 2 + b 2 − c 2 2ab. cos(A) = b 2 + c 2 − a 2 2bc. cos(B) = c 2 + a 2 − b 2 2ca picture of galatians 2:20
