Question

in △def, m∠d = 117° and m∠e = 26°. which list has the sides of △def in order from shortest to longest? answer attempt 1 out of 2 ef, fd, de ef, de, fd fd, ef, de fd, de, ef de, fd, ef de, ef, fd

Explanation:

Step1: Find angle F

The sum of angles in a triangle is 180°. So, $m\angle F=180^{\circ}-(m\angle D + m\angle E)=180^{\circ}-(117^{\circ}+ 26^{\circ}) = 37^{\circ}$.

Step2: Recall angle - side relationship

In a triangle, the side opposite the smallest angle is the shortest and the side opposite the largest angle is the longest.
Since $m\angle E

Answer:

FD, DE, EF
