Question

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 sun. Using complete sentences, explain how the scientist can use only these two measurements to calculate the distance between the moon and the sun.

Answer 1

cos x= y/(distance between sun and moon)

Answer 2

i have to explain it all in sentences though and i dont get this stuff that much can u explain it like that for me

Answer 3

let me put it this way. The angle x is known and distance y ..So using the trigonometric function for adjacent by hypotenuse.the hypotenuse is found which is the distance between the sun and the moon as shown in the figure

Answer 4

so se that as my a i put it in my own words or that not the answer

Answer 5

y= Distance between earth and sun
Secant x= Distance between moon and sun/y
y*secant x= distance between moon and sun
there you go
