Question

list the angles of △abc from the smallest to the largest.
\\(\overline{ab}=17, \overline{bc}=21, \overline{ac}=18\\)
c,b,a
a,c,b
a,b,c
b,a,c

Explanation:

Step1: Recall angle - side relationship

In a triangle, the smallest angle is opposite the shortest side and the largest angle is opposite the longest side.

Step2: Identify side lengths

Given \(AB = 17\), \(AC=18\), \(BC = 21\). So \(AB

Step3: Determine angles

The angle opposite \(AB\) is \(\angle C\), the angle opposite \(AC\) is \(\angle B\), and the angle opposite \(BC\) is \(\angle A\). So \(\angle C<\angle B<\angle A\).

Answer:

A. C,B,A
