Answer:
tan D = 12/5
Step-by-step explanation:
Recall trigonometric ratios or SOH - CAH - TOA. The reference angle whose value inside of the parenthesis in any trigonometric function (i.e. sin(x), cos(23 deg), [tex]tan(\frac{\pi }{2} )[/tex]), is used when identifying the adjacent and opposite side lengths of the angle.
In this case, D is the reference angle, so line EF is the opposite side length and line ED is the adjacent one. So,
[tex]tan(D)=\frac{EF}{ED} =\frac{12}{5}[/tex].
