I need help, it has one side with six inches and what is the nearest ten.
Since it is equiangular, it is also equilateral. Since one side is 6 inches, all 3 sides are also 6 inches. To find the height, we can use Pythorean Theorem. Since the hypotenuse is 6, and one leg is 3, c^2 - b^2 = a^2, 36 - 9 = 27. Which means a^2 = 27, and so simplifying to the nearest tenth gives us 5.2 inches.
