Hiican you help me with this sumtwo equal sides of a triangle are each 5 meter less than twice the third side.if the perimeter of the trangle is 55m. find the length of its side?

Answer»

Let the THIRD SIDE be a
Perimeter is sum of all sides
55= a+( sum of other TWO sides)
Other two sides are EQUAL and 2a-5 ( 5m less than TWICE the third)
a+2a-5+2a-5=55
5a-10=55
5a=55+10
a=65/5=13
Hence the length of the side is 13m

Hope this helps.
