PLEASE HELP ILL GIVE BRAINLIEST!!List the sides of ∆DEF in order from shortest to longest if m∠D = 20, m∠E = 120, and m∠F = 40.

zvonat [6]

Answer:

In triangle DEF:

Given: $m\angle D = 20^{\circ}$ , $m\angle E= 120^{\circ}$ and $m\angle F = 40^{\circ}$

To list the sides of a triangle in order from shortest to longest.

In the Figure as shown below :

If one of the angle of a triangle is larger than, then the sides opposite the larger angle is longer than the side opposite to the shorter

$m\angle D < m\angle F < \angle E$

$\text{EF} < \text{DE}$

Therefore, the list of the sides of a triangle DEF in order from shortest to longest is, $\text{EF} < \text{DE}$
