Question

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?

Answer 1

Answer:

160/7 or 22.85 is the measure of the two equal sides and 65/7 or 9.3 is the measure of third side.

Step-by-step explanation:

• let x is the measure of the two equal side each.
• now, the perimeter is 55 m.
• the third side is 55-2x .
• A.T.Q => x=3(55-2x)-5
• => x=165-6x-5
• => x=160-6x
• => 7x=160
• => x=160/7 or 22.85 m
• other side or third side is 65/7 or 9.3 m.(Ans.)
