In doing so I will guide you through a step by step … WebbA tangent of a circle is a straight line that touches the circumference of the circle at only one point. The angle between a tangent and radius is 90 90 degrees. Tangents which meet at the same point are equal in length. WebbThe area of an equilateral triangle with side length s is s²√3/4. Since we know the areas of these triangles, we can solve for their side lengths: s²√3/4=9√3. s²/4=9. s²=36. s=6. So the triangles have sides of length 6. And when follow a diameter of the circumcircle, we trace two sides of equilateral triangles. paint your wagon songs lyrics
