Question

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

Answer 1

as shown below???

Answer 2

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 3

You have the angle and adjacent side, you can easily calculate the rest. Use your tri functions.

Answer 4

this is not a math question...

Answer 5

ummm yea it is....

Answer 6

Yes it is

Answer 7

What can you tell me about this?

Answer 8

y= Distance between earth and sun Secant x= Distance between moon and sun/y y*secant x= distance between moon and sun?

Answer 9

Do you know how to help me on this problem?

Answer 10

Answer 12

I need help

Answer 13

tan x = opposite side/ adjacent side

Answer 14

Ok I get that....

Answer 15

which side is known?

Answer 16

I told you earlier :P

Answer 17

what do you mean which side is known there is a y on one of the sides does that mean its known

Answer 18

What has the scientist measured already?

Answer 19

the angle x and the distance y between the Earth and the sun

Answer 20

So you have 2 knowns, now use your trig functions to figure out the other unknowns. Don't over complicate the problem :p

Answer 21

Sorry but what are the trig functions?

Answer 22

Sinx, cosx, tanx, etc.

Answer 23

How do i use them in this problem can you show me please

Answer 24

solve an equation for the distance between earth and moon

Answer 25

OK..

Answer 26

HAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAH.....

Answer 27

im so confused

Answer 28

blink.

Answer 29

shut up

Answer 30
