Answer:
6 cms.
Step-by-step explanation:
If the side of an equilateral triangle is 2x cm then its height is √3x and its base is 2x.
Area = 1/2 * base * height
9√3 = 1/2 * 2x * √3x
9√3 = x * √3x
9 = x^2
x = 3
So length of each side = 2*3 = 6.
x = 9
Answer:
22
Step-by-step explanation:
X+y=11
22x+15y=228
y=11-x
22x+15y=228
22x+15(11-x)=228
22x+165-15x=228
7x+165=228
7x=63
x=9
9+y=11
y=2
The solution to the system of equations is (9,2)
