Answer:
cos Ф = adj / hyp could be either 4/5 or -4/5.
Step-by-step explanation:
If sin Ф = 3/5, then we can assume that the opposite side is 3 and the hypotenuse is 5. Using the Pythagorean Theorem, we find that the adjacent side is 4:
√(5² - 3²) = √16 = ±4.
cos Ф = adj / hyp could be either 4/5 or -4/5.
