The moon forms a right triangle with the Earth and the Sun during one of its phases, as shown below: A scientist measures the angle x and the distance y between the Earth and the moon. Using complete sentences, explain how the scientist can use only these two measurements to calculate the distance between the Earth and the Sun.

in the triangle shown y is the opposite side to angle x and the distance earth to sun is the adjacent side so you have the opposite side, need to find the adjacent side using an angle x which ratio... I wouldn't use secant

How's this? tangent (x degrees) = opposite / adjacent tangent (x degrees) = Earth Moon Distance / Earth Sun Distance

This is the last sentence from my previous answer tangent (x degrees) = Earth Moon Distance / Earth Sun Distance So, if you can solve for Earth Sun Distance, that should be the last step in your answer. So, what is the Earth Sun distance?
