I just have a few questions
1. This figure shows circle a with inscribed RSQ.
mRSQ=24dg.
What is the measure of arc RSQ?
2. In the figure, --> TR and --> TV are secants to circle A.
m(arc)RV=99dg
m(arc)SU=45dg
What is the measure of RTV?
1. m(arc)RQ = 2m(angle) RSQ = 48°
So......m(arc) RSQ = 360 - 48 = 312°
2. m (angle)RTV = (1/2)[ m(arc)RV - m(arc)SU ] =
(1/2)[99 - 45] = (1/2)[ 54] = 27°
+48
