Question
How do you solve for this?
In the diagram below, tangent DA and secant DBC
SHOW WORK I
are drawn to circle O from external point D, such
that AC = BC.
If mBC = 152°, determine and state mZD.
In the diagram below of circle 0 with diameter BC
and radius OA, chord DC is parallel to chord BA.
B
If mZBCD = 30°, determine and state mZAOB.
In the diagram below, chords PQ and RS of circle
O intersect at T.
Which relationship must always be true?
1) RT = TQ
2) RT = TS
CHOICE #
P.
3) RT+ TS = PT + TQ
RT x TS = PTx TO
4)
In the diagram shown below, PA is tangent to
circle Tat A, and secant PBC is drawn where, point
B is on circle T.
