Question

A right angle triangle is shown with the Earth at the right angle. The acute angle between the line joining the Earth and the sun and the sun and the moon is x degrees. The distance between the Earth and the moon is y

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.

Answer 1

he uses trigonometry
tan x = y / d where d = distance between earth and sun
so d = y / tan x
