Question 761049: find the length of altitude of an equilateral triangle of side 36 cm each?

You can put this solution on YOUR website!
Drawing an altitude from the middle of one
of the sides of the equilateral triangle to a
vertex creates a right angled triangle.
Base = 36/2 = 18 cm
Hypotenuse = 36cm
36^2 - 18^2 = altitude^2
Altitude^2 = 972
Altitude = 31.2 (1 decimal place)
Hope this helps.
