Answer and step-by-step explanation:
The largest side of a triangle will be across from the largest angle in the triangle, and the smallest side of a triangle will be across from the smallest angle in the triangle.
Since ∠A is the smallest angle, the side across from it, BC, will be the smallest side.
Since ∠C is the largest angle, the side across from it, AB, will be the largest side.
This means that ∠B will be the middle-sized angle and the side across from it, AC, will be the medium sized side.
This means that AC>BC.
