Question

Find the value of cos(θ) for angle θ in standard position with a terminal brain that passes through the point (4,-3)

​

Answer 1

D

Explanation:

(4,-3) lies in the fourth quadrant where cos is positive

cos(θ) = adjacent/hypotenuse

hypotenuse² = 4² + 3² = 25

Hypotenuse = 5

cos(θ) = 4/5

Answer 2

-3/4

Explanation:

cos theta = (adjacent /hypothesis) =(-3/4)
