1. Which equation correctly describes the relationship between the measures of the angle and arcs formed by the intersecting secants.

 

Options- m1=1/2(m arc PQ-m arc RS), m1=1/2 m (arc) RS, m1=m (arc) PQ- m (arc) RS, m1=1/2(m arc PQ+m RS)

 

2. The sine of 37dg is equal to the cosine of what angle?

 

3. RS is tangent to circle Q at point R. What is the measure of SQR?

1.  m1=1/2(m arc PQ-m arc RS)

 

2. sine (37°)   =  cosine ( 90 - 37)°   =  cosine ( 53°)

 

3.  SQR  =  90°
