Question

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

@peachpi I'm sorry I keep asking you. I'm just really bad at geometry and I'm trying ot get out of this class today. Thank you for helping me understand how to do it instead of giving me the answer also

Answer 2

Well let's start off with this c:

It doesn't exactly ask you to solve. We're just explaining how, if they gave you the values for x and y, we would be able to find the value of the hypotneuse.

If they gave us 2 angle values, how would we find the third? Do you know?

Answer 3

It's alright if you don't know, I just want to know if you do.

Answer 4

Not really

Answer 5

Alright. We're given a 90 degree angle. If we were given x, we could do this
All the angles in a triangle add up to 180 degrees

So, we would subtract.
180 - 90= 90
90 - x = (the last angle)

See where I'm coming from?

Answer 6

yes ish

Answer 7

ish?

Answer 8

But like. I don't know how to find x

Answer 9

What part do you not understand? c:

Answer 10

We can't, lol

Answer 11

I still don't really know how to explain that xD it's a written question

Answer 12

The problem is not to find x & y, but to show how to use x and y to find the hypotneuse of this triangle.

Answer 13

Get it? cx

Answer 14

ohh ok

Answer 15

So, x is unidentified, we're using it as a variable.

You know how all the angles in a triangle add up to 180, right?

Answer 16

yes

Answer 17

pythagorean theorum right?

Answer 18

Or nah? lol

Answer 19

Eh it's ok. I put that down. My teacher knows I'm stupid at math anyway.

Answer 20

Alright.
It is a right triangle.
That means one of the angles is 90 degrees.
180 - 90 = 90
If we subtract 90 from x (which is unidentified) we would get that last angle

And sorry, but it isn't the pythagorean theorem. cx

If once we got x, we would use the law of sines to find the length of the moon to the earth.
To find this we set this up.
\[\frac{ SinA }{ a }=\frac{ SinB }{ b }\]Let me redraw the triangle to find the right

Sorry had to take a very important call :c

Answer 21

I'm so sorry >.<

Answer 22

It's okay, Cammy. c:

Answer 23

Thank you though.
