Question

Hello I need someone to help me with a math problem from Kahn academy​

Answer 1

Explanation:

The rule for Cos is Cosine = adjacent over hypotenuse which means which ever side is closest to the angle(24) (not hypotenuse). And the Hypotenuse which is the longest side so (25).

So now we have Cos(a) = Cos(
`(24)/(25)`) = 0.57351998607
