Answer:
A) ∠BEC is one-half of ∠BAC
B) ∠BEC = 60°
C) ∠BDC = 120°
Step-by-step explanation:
C) arc BDC = 120°
arc BEC = 360° - 120° = 240°
∠BDC = 1/2(240°) = 120°
The Answer is A because if you set it to a proportion you get 1 7/9
Answer:
Circle Area = PI * radius^2
radius = sq root (Circle Area / PI)
radius = sq root (13,266.5 / 3.14159265)
radius = 64.984 yards
Step-by-step explanation:
Complete the square since can't factor
2/2=1
add 1 to both sides
x²+2x+1-6=1
factor perfect square
(x+1)²-6=1
add 6 to both sides
(x+1)²=7
sqrt both sides
x+1=+/-√7
minus 1 both sides
x=-1+/-√7
so x=-1+√7 or x=-1-√7
