Question

In an isosceles triangle length of each equal side is 8 cm correct to the
nearest centimetre. If the perimeter of the triangle is 23 cm correct to the
nearest centimetre find the smallest possible length of the remaining side.

Answer 1

Step-by-step explanation:

To find the unknown leg length with a given base length and altitude, use the following formula: sqrt(A^2 - (B / 2)^2), where A is the altitude and B is the length of the base. For example, given an isosceles triangle with base length 6 and altitude 7, the leg lengths are: sqrt(7^2 + (6 / 2)^2) = sqrt(58) = 7.6.
