A window is in the shape of an equilateral triangle with a height of 12ft.
To the nearest tenth of a foot, how long are the sides of the triangle?
:
let s = the side of the triangle
Use pythag
s%5E2+=%28.5s%29%5E2+%2B+12%5E2+
s%5E2+=+.25s%5E2+%2B+144+
s%5E2+-+.25s%5E2+=+144+
.75s%5E2+=+144+
s%5E2+=+144%2F.75+
s%5E2+=+192
s+=+sqrt%28192%29
s = 13.9 ft
