The height of an equilateral triangle equals 3√/2 times the side length. Using 7/4 for the square root of 3, what is the approximate height in meters of an equilateral triangle with a side length of 8 meters?(1 point)
To find the height of an equilateral triangle, we can use the formula:
height = (sqrt(3) / 2) * side length
Given that the square root of 3 is approximately 7/4, we can substitute this value into the formula:
height = (7/4 * 1/2) * 8 = (7/8) * 8 = 7 meters
Therefore, the approximate height of an equilateral triangle with a side length of 8 meters is 7 meters.
