120 / 18 = 20/3
x^3 / xy = x^2 / y
20x^2 / 3y
Answer:
<h3> -3 * r
</h3>
Step-by-step explanation:
at least means it can be 57 or higher
First, we have to find the length of each side of triangle. Equilateral triangle means 3 sides r in same length, so each side will be 21 ÷ 3 = 7
Now we need to calculate the height of the triangle. We can do this by Pythagoras theorem
Let the height be h
(7/2)^2 + x^2 = 7^2
The area should be 6.0621778265
Or u can say 6.06 corrected to 3 sig fig
