Question

The perimeter of an isosceles triangle is 18cm. If one of the equal sides is 23/4cm long, find the measure of third side.

Answer 1

$here \: is \: your \: answer \\ perimeter = 18 \: cm \\ let \: the \: other \: side \: of \: isosceles \: triangle \: be \: x \\ two \: equal \: side \: of \: isosceles \: triangle \: are \: 23 \div 4 \\ so \\ x + 23 \div 4 \: + 23 \div 4 = 18 \\ x + 23 \div 2 = 18 \\ x = 18 - 23 \div 2 \\ x = (36 - 23) \div 2 \\ x = 13 \div 2 \\ i \: hope \: my \: answer \: will \: help \: you$
