A shooting star forms a right triangle with the Earth and the sun as shown below:
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 sun and the shooting star.

Best ResponseYou've already chosen the best response.1you have a right triangle the trig ratios from a right triangle are: sin A = opposite/hypotenuse cos A = adjacent/hypotenuse tan A = opposite/adjacent given angle "x" and adjacent side "y", we want to find opposite side BA thus we use the tangent ratio tan(x) = BA/y solving for unknown side BA BA = y*tan(x)

Best ResponseYou've already chosen the best response.1No tangent is wrong I pretty sure its Cosine

Best ResponseYou've already chosen the best response.0yeah i think you would use cosine because you have the adjacent side and you are trying to find the hyp

Best ResponseYou've already chosen the best response.0so i could say Because the scientist is given the adjacent side and they want to find the hyp they would need to use cos. Cos= adj/hyp.
