Solution We can use a method similar to the one used to solve Example 1.8 in Section 1.2. That is, draw a right triangle and interpret cos θ as the ratio adjacent hypotenuse of two of its sides. Since cos θ = − 4 5, we can use 4 as the length of the adjacent side and 5 as the length of the hypotenuse.
