Question

The 2 equal sides of an isosceles triangle are 5.7 cm each. The base is 7 cm. What is the height?

Answer 1

`h=2/5sqrt2sqrt11sqrt23`

Explanation:

Let A, B, C be vertexes of the triangle. Normal penpendicular and median on nonequal side are the same lign segment in isosceles triangles. Then:

`color(white)(xx)3.5^2+h^2=5.7^2`

`=>h=sqrt20.24`
`=>h=2/5sqrt2sqrt11sqrt23`
