Question

name one angle linear to ∠a. ∠? enter the angle letter.

Explanation:

Step1: Recall the definition of linear - pair angles

Two angles are linear - pair if they are adjacent angles formed by two intersecting lines and their sum is \(180^{\circ}\).

Step2: Identify the adjacent angle to \(\angle A\)

Looking at the intersection point of the lines, \(\angle A\) and \(\angle B\) are adjacent angles formed by the intersection of the two lines.

Answer:

\(\angle B\)
