Question

what is the side adjacent to ∠a? bc ∠c ac ab

Explanation:

Step1: Recall adjacent - side definition

In a right - triangle for an acute angle, the adjacent side is the non - hypotenuse side that touches the angle.

Step2: Identify sides in right - triangle ABC

In right - triangle \(ABC\) with right - angle at \(C\), for \(\angle A\), the hypotenuse is \(AB\). The sides that touch \(\angle A\) are \(AC\) and \(AB\). Since \(AB\) is the hypotenuse, the adjacent side to \(\angle A\) is \(AC\).

Answer:

C. AC
