Question

In ΔDEF, sin D=24/25. What is cos E? [Worth 20 points]

Answer 1

The value of cos E is $\frac{24}{25}$. The correct option is A. $\frac{24}{25}$

Trigonometry

From the question, we are to determine the value of cos E

From the given information, we have

$sin \ D=\frac{24}{25}$

By SOH CAH TOA

Opposite = 24

Hypotenuse = 25

Thus, considering the diagram

/EF/ = 24

and

/DE/ = 25

By SOH CAH TOA

$cos \ E =\frac{/EF/}{/DE/}$

∴ $cos \ E =\frac{24}{25}$

Hence, the value of cos E is $\frac{24}{25}$. The correct option is A. $\frac{24}{25}$
