Question

equal sides of an isosceles triangle are given as 30 cm each if the perimeter of the triangle is 67 cm, find the third sides​

Answer 1

`\boxed{\pink{\sf Value \ of \ third \ side \ is \ 7cm . }}`

Explanation:

According to Question , equal sides of an isosceles triangle are given as 30 cm each if the perimeter of the triangle is 67 cm . And we need to find the third side .

Let us take the third side be x.

By Question ,

`\implies Perimeter_(\triangle)= x + 30 cm + 30cm \\\\\implies 67cm = 60cm + x \\\\\implies x = 67cm - 60cm \\\\\underline{\boxed{\red{\tt\implies x = 7cm. }}}`

Hence the value of third side is 7cm.
