What are the coordinates of point (x, y) on the terminal ray of angle

Option 1. (-5, 12)

Step-by-step explanation:

Here given values of the angles are csc∅ = 13/12 Or sin ∅ = 12/13

sec ∅ = -13/5 Or cos ∅ = -5/13

cot ∅ = -5/12 Or tan ∅ = -12/5

As we know cos ∅ = x-coordinates / y-coordinates which = negative value

tan ∅ = y-coordinates / x - coordinates = negative value

Now we can say the angle lies in second quadrant. So the point (x, y) will be  (-5, 12).

Therefore answer is option 1.  

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
