Question

10. Two equal sides of a triangle are each 5 meters less than twice the third side. If the
perimeter of the triangle is 55 meters, find the length of its sides? please slove this
​

Answer 1

Answer:

17,17,11

Step-by-step explanation:

Let one of the 2 equal sides be x.

side 1 = 2x-5

side 2 = 2x-5

side 3 = x

Perimeter = 55m

2x-5 + 2x-5 + x = 55

4x + x = 55

5x = 55

x=11

Side 1  = 2(11)-5 = 17 m

Side 2 = 2(11)-5 = 17 m

Side 3 = 11 m
