Answer:
Step-by-step explanation:
Triangle Area = .5 * base * height
48 = .5 * (x +4) * x
48 = (.5x + 2) * x
48 = .5x^2 + 2x
.5x^2 + 2x -48 = 0
x = 8
base = 12
It's an equilateral triangle, therefore
AB = BC = BA
We have the equation:
7033 / 10 000
x = .70330
10 000 x = 7033.0 divide both sides by 10 000
x = 7033 / 10 000
