Hello, i'm a teacher for this question and our question says that the perimeter of a triangle is 180 feet the longest side of the triangle is 9 feet shorter than twice the shortest side the sum of the lengths of the two shorter side is 30 feet more than the length of the longest side find the lengths of the sides of the triangle how we're gonna solve this question just see that we are given with perimeter of triangle is 180 fit perimeter of triangle let me write this completely a triangle so the perimeter of a triangle is set to be 180 fit all right and we have been also said that the longest side of the triangle is nine foot shorter than twice the shortest side so shortest side so the shortest side let's say this shortest side is all right this is the shortest side then after i'll be telling that this is the longest side all right so just see that the longest side of the triangle is nine feet shorter then twice the shortest side all right so the longest side is nine feet shorter than twice the shortest side and the sum of the lens of the two shorter side is 30 feet so the sum of the length of this two shorter sides is 30 fits if this is longest then these two are shorter so we'll be writing that this side can be written as 30 minus x all right why so because because we are given with x 30 minus x so you'll be saying that this is these are the two shortest side so this is said that the sum of the of the two shorter side is 30 feet more than the length of the longest side.

Okay, 30 feet more than the longest side.
02:26
Alright, the sum of the length of the two shorter side.
02:29
Let's say this is y.
02:31
Let's say this is y.
02:33
So the sum of the lens of the two shoulder side is 30 feet more than the length of the longest side.
02:41
So 30 feet more than the longest side.
02:47
So the sum of the lens of the two shoulders side.
02:49
Shorter side is 30 feet more than the length of the longer side.
02:54
So the shorter sides, shorter sides is 30 foot more than the longer side.

All right...
