Answer 2

Sin A =
`(12)/(13)` ; Cos A =
`(5)/(13)`

Explanation:

The sine of a given angle is
`(opposite)/(hypotenuse)`, using the lengths corresponding to them. In this case, the side length opposite to angle A is 24, and the hypotenuse is 26. This gives
`(24)/(26) = 12/13`.

The cosine of a given angle is
`(adjacent)/(hypotenuse)`, using the lengths corresponding to them. In this case, the side length adjacent to angle A is 10, and the hypotenuse is 26. This gives
`(10)/(26) = 5/13`.
