Area of an oblique triangle- Finding the area of a triangle without the height

An oblique triangle is a triangle without a 90 degree angle.
The form for area for an oblique triangle equals 1/2 b * c (sin A)
The equation gives us a way to find the area of the triangle without needing to find the height of the triangle.
This means we can find the area of oblique triangles without needing to create right triangles.
