Triangle DEF is a right triangle. We will use the Pythagorean theorem to find the length of the Hypotenuse DE:

DE² = 7² + 24²

DE² = 49 + 576

DE² = 625

DE = 25

sin D = Opposite / Hypotenuse = 24 / 25

tan D = Opposite / Adjacent = 24 / 7

sin E = Opposite / Hypotenuse = 7 / 25

Answer:

A) sin D = 24 / 25

C) tan D = 24 / 7

D) sin E = 7 / 25.
