Question

question find the value of cos d rounded to the nearest hundredths, if necessary. answer cos d =

Explanation:

Step1: Recall cosine ratio formula

In a right - triangle, $\cos\theta=\frac{\text{adjacent}}{\text{hypotenuse}}$. For $\angle D$, the adjacent side to $\angle D$ is $24$ and the hypotenuse is $26$.

Step2: Calculate cos D

$\cos D=\frac{24}{26}=\frac{12}{13}\approx0.92$

Answer:

$0.92$
