the height of the triangle gives us the right triangles we need to prove this. we use the reference angle using sin which is opposite over hypotenuse.






4. Area of formulas: how is the "area of an oblique" triangle derived? how does it relate to the area formula that you are familiar with?

an oblique triangle is a triangle that has no right triangle in it. the area of a triangle is base time height divided by 2. if you have a base and angle and a side you have enough to find the area.
