Help, and can you show your work?

Answer:
c
Step-by-step explanation:
[tex]sin = \frac{opposite}{hypotenuse}[/tex]
it wants us to find sin a
the opposite of a is 24 and the hypotenuse is 26
so sin A = 24/26
[tex]cos = \frac{adjacent}{hypotenuse}[/tex]
it wants us to find cos a
the adjacent of a is 10 and the hypotenuse is 26
so cos A = 10/26
have a great day :D
