Find out the what does ∠ ACB equal .
To prove
As given
∠ AOB =80°
By using the relationship between the inscribed angle and central angle.
Here
Inscribed angle = ∠ACB
Central angle = ∠AOB = 80°
∠ACB = 40°
Option (A) is correct .
f(x) = - 2/3x + 5; f(5/2)
substitute 5/2 in for x:
f(5/2) = -2/3(5/2) + 5
simplify the right side:
f(5/2) = -5/3 + 5
f(5/2) = 10/3
answer:
i hope this you!
the answer is y = 11.54
hope this : )
