Question

The moon forms a right triangle with the Earth and the sun during one of its phases, as shown below.

Answer 1

Shown below?
I can't see anything <.< >.>

Answer 2

calm wait

Answer 3

Well I'm guessing you have to use trig triangles, so soh cah toa.

Answer 4

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 5

SOH do you see what you have to use here?

Answer 6

ok so we're assuming that the scientist knows the angle and the distance from earth to the moon and we want to explain how to find the distance from earth to the sun
so they gave us those to pieces of information
but there's one other important thing they told us and that we are dealing with a right triangle.

Answer 7

so, what are your ideas about how we could solve this?

Answer 8

I've given you SOH many hints :P

Answer 9

ok so that symbol I wrote down inside all of the trig functions is called theta and that's what ill call the angle for now
just so we don't confuse it with the length x
and the hypotenuse i called h
so we are trying to find the value of x correct? ;)
