Answer:

Step-by-step explanation:
Given: (8,-15) is on the terminal ray of angle
To find: All the trigonometric ratios
Solution:
Trigonometry is a  branch of mathematics that explain relationship between the sides and angles of triangles.
 If (x, y) lies on the terminal side of  θ  then

Carlita was either sipping the hot chocolate while she was out, or else 
approximating the numbers.  The exact number she reported is not 
possible.  To see why, I'll do it strictly by the math:
Robins  =  5 times
Cardinals  =  1 time
Total birds  =  6 times  
6 times  =  25 birds
Divide each side by 6 :   1 time  =  25/6  =  4-1/6 birds
Robins =  5 times  =  20-5/6 of them
Cardinals  =  1 time  =  4-1/6 of them
Total:  (20-5/6) + (4-1/6)  =  25 birds.
How many more robins than cardinals  = (20-5/6) - (4-1/6) = 16-2/3 more.  
The math works out fine.  But if the numbers she reported are true,
then some of what she saw was partial birds ... legs, or feathers,
things like that.  Eeeew.   I don't want to talk about it.
