Question

question 2 (1 point)
in △abc, ab = 12, bc = 4 and ac = 9. which is the smallest angle?
o a angle b
b angle c
o c angle a

Explanation:

Step1: Recall the triangle side - angle relationship

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

Step2: Identify the shortest side

Given \(AB = 12\), \(BC=4\), and \(AC = 9\). The shortest side is \(BC = 4\).

Step3: Determine the angle opposite the shortest side

The angle opposite side \(BC\) is \(\angle A\) (using the notation that in \(\triangle ABC\), side \(BC\) is opposite \(\angle A\), side \(AC\) is opposite \(\angle B\), and side \(AB\) is opposite \(\angle C\)).

Answer:

C. angle A
