Answer 2

Are you studying trigonometry?

Answer 3

Yea

Answer 4

have you learned SOH CAH TOA ?

Answer 5

sine, cosine, and tangent of an angle.

Answer 6

ok. Look at the triangle in your problem. You (or the scientists) know 2 things
and there is one thing you don't know (but want to).. an unknown side

each of SOH CAH TOA use 3 things (angle and two sides)

so the idea is to pick one of the 3 that use the same 3 things that your problem uses.

Answer 7

in other words, you want to know AB, and you do know side y, and angle x
put your self at angle x, and label the sides AB and y as opposite and adjancent

Answer 8

Yea thats what i was going to say : P

Answer 9

Yea the adajat is BC and the opposite is A

Answer 10

A is a point, so I would say side AB
or give the side a "name" like z

Answer 11

Yea ok

Answer 12

which of the 3 uses the opposite side and the adjacent side ?

Answer 13

id say opposite would be BA? and the adjacent would be BC

Answer 14

yes, and because they named BC "y" , you could call BC "y"

Answer 15

which of SOH CAH TOA should we use ?

Answer 16

We would use cah?

Answer 17

we want the one that has opposite (an O) and adjacent (an A)
cah has Adjacent and Hypotenuse

Answer 18

oh to TOA

Answer 19

yes, and TOA is short for
tan(angle) = opposite/adjacent

the angle is called "x'
the opposite is side AB
the adjacent is side BC , but they say its length is y, so we will use y
\[ \tan x = \frac{AB}{y} \]

Answer 20

if you know algebra, then you would "solve for AB" by multiplying both sides by y

Answer 21

Ok, and yea ik algerbra

Answer 22

*algebra

Answer 23

you should get
y tan x = AB
or
AB = y tan x

which means, to find the distance from earth to the shooting star
multiply t times tangent of x
