 Question 135399: The entrance to a tent is the shape of an equilateral triangle. If the base of the tent is 18 feet wide, then how tall is the tent?Answer by stanbon(57395)   (Show Source): You can put this solution on YOUR website!The entrance to a tent is the shape of an equilateral triangle. If the base of the tent is 18 feet wide, then how tall is the tent? ------------------------- Draw the equilateral triangle. Draw a perpendicular bisector from the top vertex to the base. You now have two right triangles. Use Pythagoras to solve for the height. EQUATION: h^2 + 9^2 = 18^2 h^2 = 18^2 - 9^2 h^2 = 243 height = sqrt243 = 15.59 feet ============================== Cheers, Stan H.
