Question

given each reference angle, label the hypotenuse, adja b.

Explanation:

Step1: Identify the hypotenuse

In a right - triangle, the hypotenuse is the side opposite the right angle. In triangle \(ABC\) with \(\angle B = 90^{\circ}\), the hypotenuse is \(AC\).

Step2: Identify the adjacent side to \(\theta\)

The adjacent side to an angle \(\theta\) in a right - triangle is the non - hypotenuse side that forms the angle \(\theta\). For angle \(\theta=\angle A\), the adjacent side is \(AB\).

Step3: Identify the opposite side to \(\theta\)

The opposite side to an angle \(\theta\) in a right - triangle is the non - hypotenuse side that does not form the angle \(\theta\). For angle \(\theta = \angle A\), the opposite side is \(BC\).

Answer:

Hypotenuse: \(AC\); Adjacent side to \(\theta\): \(AB\); Opposite side to \(\theta\): \(BC\)
