What is the radius of a tipi with a height of 24 ft tilt with support posts lodgepole pine intersecting at an angle of 80 °? Round your answer to the nearest foot
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 )
`AB=24 xx .839`
Thus nearest feet radius AB=20 feets.
