Assuming you mean the central angle, semicircles have central angles of .
Since A = L * W, W = A / L.
Here, W = (6 1/8 ft^2) / (3 1/2 ft) = 1 3/4 ft.
The garden width is 1 3/4 ft.
If the triangle is equilateral it means all the sides are the same length.
A triangle has three sides. if each side is 2/8cm then the total perimeter if 3*2/8 = 6/8 = 3/4
We can start by getting rid of parenthesis:
4x-3x+6=21
Then we can combine like terms:
x=21-6
x=15
So our end product is x=15.
Hope I helped soz if I'm wrong ouo.
