Good question!

First of all, you need to be aware of the following trigonometrical ratios\functions:

For angle A:

adjacent=12
opposite=35
hypotenuse=37

Hence:
cos(A)= \frac{12}{37} &#10;\\~\\&#10;sin(A)= \frac{35}{37} &#10;\\~\\&#10;tan(A)= \frac{35}{12}

I hope that helps!



I am with you if you faced any difficulties!
