Calcium helps to maintain the strength of your bones and teeth, keeping them from becoming weak and brittle. Many dairy products contain a fair amount of calcium in them, including milk and cheese. Many vegetables also contain calcium without the high fat content, such as broccoli and kale.
Hope this helps!
Note.... sin (-θ) = -sin(θ)
And tanθ =√15 / 15 = 1 / √15
So
-sin (θ) = -1/4 ⇒ sin (θ) = 1/4
And
tan (θ) = sin (θ) / cos(θ) rearrange as
cos (θ) = sin (θ) / tan (θ) = (1/4) / (1/ √15) = (1/4) * (√15 / 1) = √15 / 4 ⇒ C
