Question

In triangle EFG, the measure of Angle E=3x-24, the measure of Angle F=7x-30. The measure of Angle G=4x+10. List the sides in order from longest to shortest.

Answer 1

Think about the sum of interior angles in a triangle. You should be able to find x.

Answer 2

But the angles are 3x-24 and 7x-30

Answer 3

Oh, sorry. Minor typo on my part. In any case, the sum of the interior angles is 180, so you have
\[(3x-24)+(7x-30)+(4x+10)=180\]
