Question

Find the measures of the indicated angles in circle O. Which statement is NOT true? (The figure is not drawn to scale.)
A) a= 53 B) b=106 C) c=73

Answer 1

This is just waht @phi said about inscribed angles.

Answer 2

Basically, I'm applying the theorem where the intercepted arc is twice the measure of the inscribed angle.

Answer 3

The incorrect statement is C) 73. The correct answer is 74... so close, yet so far.

Answer 4

so wait its 106 or 73?

Answer 5

No, angle c = 74

Answer 6

ohhhh okay got it

Answer 7

Write the standard equation for the circle.
center (10, –6), r = 6
A) (x+10)^2+(y-6)^2=6
B) (x+6)^2+(y-10)^2=36
C) (x-10)^2+(y+6)^2=36

Answer 8

C
(x-h)2+(y-k)2 = r2
(h,k) = center
r = radius
