    A scientist measures the angle x and the distance y between the Earth and the Sun. Using complete sentences, explain how the scientist can use only these two measurements to calculate the distance between the moon and the Sun.

    This is my answer so far: The scientist should use the cosine function (cos = adj/hyp) because we already know the adjacent, and the hypotenuse is what we need to find. If we use cosine, we can find the hypotenuse while working with the problem.

    Am I taking the right approach by using cosine?

    Okay thank you! But, should I write anything else in my answer?

    \[\cos(x) = (\frac{ y }{ hypotenuse })\]

    And is this what you mean by "cos x = y/distance moon to sun"?

    Okay, but I'm not sure how to describe that. I just started doing trig. Can you give me a hint on what the relationship is?

    what I am getting at is why the cosine rule

    Oh, okay, but my class did not really teach me "rules" that relate to the trig functions. All they said was that cosine is the ratio of side adjacent the angle to the hypotenuse.
