Answer:

⦿ 24/25

Explanation:

cos A = adjacent/hypotenuse

For angle A, the adjacent leg is AB that measures 24.

The hypotenuse is AC.

Since we have the lengths of the two legs, we can use the Pythagorean theorem to find the length of the hypotenuse.

a² + b² = c²

7² + 24² = c²

49 + 576 = c²

c² = 625

c = √625

c = 25

cos A = adj/hyp

cos A = 24/25
