The diagram shows rays of light from a point source, P, that reach a detector, D, along two paths. One path is a straight line,
while the other is bent by reflection off a mirror. What is the value of b, correct to one decimal place? Assume that all the points in the diagram lie in the same plane. 5.4
This can solved using the cosine law which is: c² = a² + b² - 2ab cos θ Using the values given from the problem 6² = b² + b² - 2bb cos 112.62 And solving for b 36 = 2b² - 2b² cos 112.62 b = 3.6

Well, 3/12 is like 1/4. So if only one fourth of her bows are red, then that means 3/4s aren't. 1/4 is the same as 25%. So 75% of Janica's bows aren't red.
