Fill in the blank. given o below, you can conclude that ac is congruent to a. dfb. obc. abd. o

A. DF

Step-by-step explanation:

The length of OB is the same as OE, and the angle that AC makes with OB is the same as the angle DF makes with OE.  This means the length of both chords, AC and DF, must be the same.

We can conclude that . Option (A) is correct.

Further Explanation:

Given:

The options are as follows,

A.

B.

C.

D.

Explanation:

The length of OE is

The length of OB is

The length of OB and OE is

AC and FD are the chords of the circle.

OE and OB are the perpendicular bisector of the chords AC and FD respectively.

The length of the perpendicular bisectors of chords is

The given chords of the circle are equidistant from the center of the circle.

We can conclude that . Option (A) is correct.

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
