Question

use the image to answer the question.
which side length is adjacent to angle d?
(1 point)
the side length adjacent to angle d is

Explanation:

Step1: Recall adjacent side definition

In a right triangle, the adjacent side to an acute angle is the leg that forms the angle (excluding the hypotenuse). For angle \( D \), the right angle is at \( E \), so sides: \( DE = 12 \), \( EF = 5 \), hypotenuse \( DF = 13 \).

Step2: Identify adjacent side to \( D \)

Angle \( D \) is formed by sides \( DE \) and \( DF \). The leg adjacent (not hypotenuse) is \( DE \), length 12.

Answer:

12
