Question

Am I correct here with 2/5

Answer 1

First you'd have to begin by finding r.

Answer 2

I see

Answer 3

You're given x, given y, and \[r=\sqrt{x^2+y^2}\]

Answer 4

By graphing your points, you'll see that it forms a right triangle. Thats when you use your trig ratios to find whatever you're looking for. In this case it's \(\tan(\theta)\).

Answer 5

So first of all, what is r = ?

Answer 6

29

Answer 7

rather, \(r=\sqrt{29}\).

Answer 8

Good.

Answer 9

Now do you know SOHCAHTOA?

Answer 10

yes

Answer 11

You're looking for \(\tan(\theta)\). Which part of SOHCAHTOA does that follow?

Answer 12

H or T if I remeber

Answer 13

Hmm.. not quite.

SOH : \(\sin\theta = \dfrac{opp}{hyp}\)

CAH: \(\cos\theta = \dfrac{adj}{hyp}\)

TOA: \(\tan\theta = \dfrac{opp}{adj}\)

Answer 14

I said T

Answer 15

I wasn't quite sure what you were referring to with 'H'

Answer 16

yes my mistake

Answer 17

But yes, \(\tan\theta = \dfrac{opp}{adj}\).

Answer 18

Now we draw out our triangle and fill in the values.

Answer 19

person your a good teacher
