Answer:
2) the quadratic has one x intercept
Step-by-step explanation:
D = 0 => has twin quadratics as one x intercept
The answer would be 24.6 cm
200×180 =36,000
36,000 / pi (approx 3.14)= 11,459.1559026
If all the angles are 60 degrees, this is an equilateral triangle. This means that all the sides have the same lengths. Whatever length side a is, b and c have the same length.
Hope this helps :)
