Question

An isosceles triangle has sides A, B, and C, such that sides A and B have the same length. Side C has a length of `5` and the triangle has an area of `40`. What are the lengths of sides A and B?

Answer 1

`sides A and B = 16.194`

Explanation:

Let h = height of the triangle
Area = `1/2xx5xxh=40`
`h=16`
side A = side B = `sqrt(16^2+(5/2)^2) = 16.194`
