Answer:
Answer choice A (<A,<B,<C)
Explanation:
I have attached a rough drawing of this type of triangle (not to scale)
The longest side of the triangle is always the side opposite of the largest angle. Since side AB is the longest, we know that angle C is the largest angle.
This is also true for the smaller angle. The smallest angle is always opposite the shortest side. The shortest side is side BC. The angle opposite this side is angle A, meaning angle A is the smallest.
Hope this helps :-)
