Web15 sep. 2024 · Since cos θ = − 4 5, we can use 4 as the length of the adjacent side and 5 as the length of the hypotenuse. By the Pythagorean Theorem, the length of the opposite side must then be 3. Since cos θ is negative, we know from Figure 1.4.5 that θ must be in either QII or QIII. Thus, we have two possibilities, as shown in Figure 1.4.8 below:
