Question

the perimeter of an isosceles triangle is 32.7 in. if the length of it's base is 9.5in. find the length of each of the other two sides

Answer 1

length of other 2 sides = 11.6 in

Explanation:

an isosceles triangle has 2 congruent legs

let the length of the congruent legs be x

then given perimeter = 32.7 and base = 9.5

x + x + 9.5 = 32.7

2x + 9.5 = 32.7 ( subtract 9.5 from both sides )

2x = 23.2 ( divide both sides by 2 )

x = 11.6

each of the 2 legs is 11.6 in
