There aren’t any options, use a picture?
In this problem, an angle like angle BAC where the
vertices like on the circle itself is called the inscribed angle.
While angle BOC, where O is the center of the circle, is
called the central angle.
Using Proposition III.20 from Euclid's Elements, this is called
the Inscribed Angle Theorem wherein:
∠BOC = 2∠BAC
or ∠BOC / 2 = ∠<span>BAC</span>
300,022,000.
Don't quote me on that, I'm really not all that good at math.
Answer:
question wrong
Step-by-step explanation:
2 same angles

Answer:
x = 10
Step-by-step explanation:
To find x, write a proportion between the side lengths for the similar triangles in the figure.

To solve, cross multiply and isolate x.
(x+5)(12) = 18(x)
12x + 60 = 18x
60 = 6x
10 = x
