Answer 1

Hm

Answer 2

Hm

Answer 3

Im confused

Answer 4

Same hold on i've got someone assisting me

Answer 5

Thank you (:

Answer 6

tan theta=1/3

Answer 7

My internet just got back up

Answer 8

i don't understand how he did this

Answer 9

A terminal angle

Answer 10

So now we just use SOHCAHTOA to find

sin:

cos:

tan:

Answer 11

\[\sf \text{ sin }\theta = \frac{opp}{hyp} \\ \\ cos ~\theta = \frac{adj}{hyp} \\ \\ tan ~\theta =\frac{opp}{adj} \]

Answer 12

use the Pythagorean theorem to find the radius, r²= x² + y²

Answer 13

so now you just gotta plug in x and y from your point into the above formula
