Answer:
60°
Step-by-step explanation:
Let angle BAE = angle ACD = x
BCD = AEC = 60°
EAC + FCA + ECF + AEC = EAC + x + 60° + 60° = 180°
EAC = 60° - x
BAC = EAC + BAE = 60° - x + x = 60°
A or B
x = - 3
To find the zeros set f(x) = 0, that is
(x + 3)(x - 7)(x + 5) = 0
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 7 = 0 ⇒ x = 7
x + 5 = 0 ⇒ x = - 5
y = -53x
since 0,0 is a point, there is no b, and -5/3 times 3 is -5
