tatyana61 [14]3 years ago
8 0

Step-by-step explanation:

1. x² = V12²+16²

= V144+256

= V400

x² = 20

2. x² = V14²-11²

= V196-121

= V75

x = V25×3

= 5V3

3. x² = V9²-7²

= V81-49

= V32

x = V16×2

= 4V2

Given right triangle jkl, what is the value of cos(l)? five-thirteenths five-twelfths twelve-thirteenths twelve-fifths
kykrilka [37]

The value of the cosine ratio cos(L) is 5/13

<h3>How to determine the cosine ratio?</h3>

The complete question is added as an attachment


Start by calculating the hypotenuse (h) using

h^2 = 5^2 + 12^2

Evaluate the exponent

h^2 = 25 + 144

Evaluate the sum

h^2 = 169

Evaluate the exponent of both sides

h = 13

The cosine ratio is then calculated as:

cos(L) = KL/h

This gives

cos(L) =5/13

Hence, the value of the cosine ratio cos(L) is 5/13
