Which circle shows Arc A B that measures 60°?

Circle O is shown. Line segments A and B are shown. The angle between the 2 segments is 60 degrees.
Circle O is shown. Line segment A is a tangent and line segment B is a secant. The angle between lines A and B is 60 degrees.
Circle O is shown. Line segments A O and B O are radii. Angle A O B is 60 degrees.
Circle O is shown. Line segment A Y is a secant. Line Y B is a diameter. Angle A Y B is 60 degrees.

The awnser is C the one that has all point connect A,B and O.

Step-by-step explanation:

I took the test got it wrong and it showed the awnser

C just took the Unit Test Review

Step-by-step explanation:

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
