7.79cm It is an equilateral triangle so it has 3 equal sides. That means each side is 9cm. <span>
Now draw a line from the top of the equilateral triangle to the base, and dividing it into two. You will have made two smaller triangles, with sides 9, 4.5, and h (the one you want to find).
A line drawn from the apex of an equilateral triangle to the midpoint of the base is perpendicular to the base, so you can use Pythagoras' Theorem!
4.5^2 + h^2 = 9^2
h = sqrt(9^2 - 4.5^2)
Therefore, the height is 7.79cm (2 decimal places)</span><span>

Answer:
The square root of 32 by 3 is 5.657
Step-by-step explanation:
102.
102 is the closest to a two digit number that is divisible by 2, 3, and 4.
What I did was I got the closest numbers to 99 and worked my way up.
100 didn't work
101 didn't work
102 seemed to be a good candidate
