Answer:

6.4

Step-by-step explanation:

The given triangle is a Right Angled Triangle with right angle at E.

So, measure of angle E = 90 degrees

measure of angle D = 62 degrees

measure of side FE = 12

We have to find the measure of side DE. Note that side DE is adjacent to Angle D and side FE is opposite to angle D. So we can use tangent ratio to find the measure of DE.

$\textrm{Tangent of angle}=\frac{Opposite}{Adjacent}\\\\tangent(62)=\frac{FE}{DE}\\\\tangent(62)=\frac{12}{DE}\\\\DE=\frac{12}{tangent(62)}\\\\DE=6.4$
