List the angles of triangle def in order from smallest to largest measure if de equals 7 ef equals 9 and df equals 3

When you illustrate the problem, an image like that shown in the picture is formed. You are asked to order the angles in increasing order. Since, it did not ask for the values, we don't have to solve it.

Note that the larger the angle, the larger its opening, thus its opposite side would be larger also. Using this analogy and referring to the picture, the order of angles should be: Angle E < Angle F < Angle D

Uneed to add them up 27+18+23=68
