Question

what is the length of the side opposite ∠b?
○ 3 units
○ 4 units
○ 5 units
○ 6 units
(image: right triangle abc with right angle at c, ac=4, bc=3, ab=5)

Explanation:

Step1: Identify ∠B's opposite side

In right triangle \(ABC\) (right-angled at \(C\)), the side opposite an angle does not form the angle. ∠B is formed by sides \(AB\) and \(BC\), so the opposite side is \(AC\).

Step2: Get length of opposite side

From the diagram, the length of \(AC\) is 4 units.

Answer:

B. 4 units
