Answer: 
<u>Step-by-step explanation:</u>
Given: cos x = 
, x is in Quadrant 4
Use Pythagorean Theorem to find sin x:
8² + y² = 17²
y² = 17² - 8²
y² = 289 - 64
y² = 225
y = 15
→ sin x = 
Use the double angle formula to find cos (2x):
C would be 16 and b would be 8 square root of 3 so the answer would be a
