Answer:
![C = 28.9](https://tex.z-dn.net/?f=%20C%20%3D%2028.9%20)
Step-by-step explanation:
Given the right angled triangle, ∆BCD, you are required to find the measure of angle C.
Apply the trigonometric ratio formula to find m < C.
Adjacent side = 7
Hypotenuse = 8
Trigonometric ratio formula to apply would be:
![cos(C) = \frac{7}{8}](https://tex.z-dn.net/?f=%20cos%28C%29%20%3D%20%5Cfrac%7B7%7D%7B8%7D%20)
![cos(C) = 0.875](https://tex.z-dn.net/?f=%20cos%28C%29%20%3D%200.875%20)
![C = cos^{-1}(0.875)](https://tex.z-dn.net/?f=%20C%20%3D%20cos%5E%7B-1%7D%280.875%29%20)
![C = 28.9](https://tex.z-dn.net/?f=%20C%20%3D%2028.9%20)

The period is the distance from one point to another point in the horizontal direction.
Amplitude is the height of the center line to the lowest peak of the highest point from the x-axis.
Using the two highest points, the first is located at X4 and the second is at X9
9-4 = 5
The period = 5
The highest point is at 6, and the lowest point is at -3, which makes the length 9.
9 /2 = 4.5
Amplitude = 4.5
Answer: period:5, amplitude: 4.5
