Question

Please help me with this​

Answer 1

Answer:

D. $Cos(Z) = \frac{5}{13}$

Step-by-step explanation:

Using trigonometric ratios formula, thus:

$Cos(Z) = \frac{Adjacent}{Hypotenuse}$

Reference angle = Z

Adjacent = 10

Hypotenuse = 26

Plug in the values into the formula

$Cos(Z) = \frac{10}{26}$

Simplify

$Cos(Z) = \frac{5}{13}$
