If ab = 8, bc = 16, and ca = 13, list the angles of abc in order from smallest to largest. options are a, b,c c, b,a b, a,c c, a,b

C , B , A

Explanation:
In any triangle, there is a direct relation between the measure of the angle and the length of the opposite side.
This means that:
- The longest side will be the one opposite to the largest angle
- The shortest side will be the one opposite to the smallest angle

In the given triangle:
- The longest side is BC, this means that the largest angle is angle A
- The shortest side is AB, this means that the smallest angle is C
- CA has an intermediate length (AB < CA < BC), this means that measure angle B will be greater than C and less than A

Based on the above, the order from the smallest angle to the largest angle will be as follows:
C < B < A

Hope this helps :)
