A tipi is cone with height 24 ft and and vertex angle 80 degree.

Since height is perpendicular to radius and bisect the vertx angle.

Thus we have a right angle triangle  say ABC , right angle at B and angle C  40 degree (half of vertex angle )



`BC tan(40^o)=AB`

`AB=24 xx .839`

`=20.13 `

Thus nearest feet radius AB=20 feets.
