I think you need the diagram
y= Distance between earth and sun Secant x= Distance between moon and sun/y y*secant x= distance between moon and sun
well you can use a trig ratio... which one would you choose
MissSunshine - y = Earth Moon distance
oh ok well wouldnt i use the equation sin(x) = d/y
y= Distance between earth and moon Secant x= Distance between moon and sun/y y*secant x= distance between moon and 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
Moo_Moo17 - What would you do next?
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?
