Hurry! 6 min ! given right triangle jkl, what is the value of cos(l)? a). 5/13 b). 5/12 c). 12/13 d). 12/5

A.

Step-by-step explanation:

For angle y in a right triangle  ,the trigonometric ratio of cos y is given by :-

Given: The side adjacent to angle L= 5 units

The side opposite to angle L =  12 units

Let h be the hypotenuse, then using Pythagoras in the given right triangle, we get

Thus, hypotenuse = 13 units

Now,  the trigonometric ratio for cos L is given by :-

Hence, the value of cos L =
