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°

 

 

 

cool cool cool
