Which trigonometric ratio is correct for triangle DEF Hint Use Pythagorean Theorem first A SinD 247 B TanD 2425 C CosE 2425 D SinE 724 class=

Respuesta :

Answer:

Cos E= 24/25

Step-by-step explanation:

Length of hypotenuse: 7^2+24^2=625. 625 square root=25

Thus, DE is 25.

Sin D= 24/25, so that is false.

Tan D= 24/7, so that is false.

Cos E= 24/25, so that is true

Sin E= 7/25, so that is false.
