Are you saying that all 3 sides of the triangle are equal, and are 10-ft each ?
In that case, if you set the triangle down on one of its sides, the vertex at the top will be 5√3 = about 8.66-ft above the table.
Square root of 75 or 8.66 rounded. Use Pythagorean Theorem.
The height of an equilateral triangle with each side measuring 10 ft is approximately 8.66 ft. This is calculated using properties of a 30-60-90 triangle derived from splitting the equilateral triangle. The height is equal to 5 3 ft, which is approximately 8.66 ft.
