The answer to your question is:
sin Ф = 12/13
cos Ф = 5/13
Step-by-step explanation:
Data
Point (5,12)
sin Ф = ?
cos Ф = ?
Process
1.- Plot the point, and draw a right triangle from the points (0, 0), (5, 0) and (5, 12). See the picture below.
2.- Calculate the hypotenuse.
3.- Calculate sin Ф and cos Ф.
c² = 5² + 12²
c² = 25 + 144
c² = 169
c = 13
sin Ф = opposite side/ hypotenuse = 12/13
cos Ф = adjacent side/ hypotenuse = 5/13
