Answer:
3/5
Step-by-step explanation:
The range of the cosine function is [-1, 1]. Since √41/5 is greater than 1, we eliminate answers a) and b) immediately.
If this angle lies in Quadrant IV, the "adjacent side" is positive. Thus, the cosine of this angle must be 3/5.
D is the correct answer
264 inches
1 foot = 12 inches
so 22 feet= 22 x 12 inches= 264 inches
12
