So now we just use SOHCAHTOA to find 

sin:

cos:

tan:

jhannybean · Answer

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

anonymous · Answer

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

anonymous · Answer

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