If then = "opposite side"/"near side'. Draw a right triangle with one vertex at (0, 0), another at (-12, 0), and the third at (-12, 5). Label the angle at the origin " ". On that triangle . What is ?

If , then [tex]csc(\theta)= -9/4[//tex]= "hypotenuse"/"opposite side". In order to draw such a triangle, we need to know the length of the "near side". Use the Pythagorean theorem.
