• Derivation of the Law of Sines: To calculate side or angle lengths of right triangles, you can set up a trigonometric ratio using sine, cosine, or tangent. However, if the triangle does not include a right angle, these basic trigonometric ratios do not apply. Triangles that do not have a right angle are called oblique triangles. Although the ...

• The tangent of an angle in this context is the ratio of the length of the side that is opposite to the angle divided by the length of the side that is adjacent to the angle. This is the same as the ratio of the sine to the cosine of this angle, as can be seen by substituting the definitions of sin and cos from above:

• Trigonometric Ratios. If one of the angles of a triangle is 90º (a right angle), the triangle is called a right angled triangle. We indicate the 90º (right) angle by placing a box in its corner.) Because the three (internal) angles of a triangle add up to 180º, the other two angles are each less than 90º; that is they are acute.

• We now use trigonometric ratios to find cos x = adjacent / hypotenuse = 2 √ (10) / 7 cot x = adjacent / opposite = 2 √ (10) / 3 Problem 4 Find the exact values of x and y. Solution to Problem 4: The sine function involves x and the hypotenuse as follows. sin 30 o = x / 10 Use sin 30 o = 1 / 2 ( see table of special angles) to find x x = 5
