Question

what is the length of the side opposite ∠b?
○ 3 units
○ 4 units
○ 5 units
○ 6 units

Explanation:

Step1: Identify the triangle's angles and sides

In triangle \(ABC\), \(\angle C\) is the right angle. We need the side opposite \(\angle B\).

Step2: Determine the opposite side

In a triangle, the side opposite an angle is the one not connected to the angle. For \(\angle B\), the side not connected to \(B\) is \(AC\), which has length 4 units.

Answer:

4 units (corresponding to the option "4 units")
