1. Triangle ABC is a right triangle with right angle at B.

AB=29cm

CB=38cm

What is the measure of C to the nearest degree?

 

2. Which equation correctly describes the relationship between the measure of inscribed angle and the measure of the intercepted arc in the figure?

 

Options- mPQR=360dg-m(arc)PR, mPQR=2(m arc PR), mPQR=1/2m(arc)PR, mPQR=m(arc)PR

3. In circle Q, what is the value of x?

1.

 

A

 

B         C

 

AB  = 29     CB  = 38

 

We can use the tangent inverse to find C

 

arctan ( 29/38)  =  C  ≈  37.35°

 

 

2.  mPQR=1/2m(arc)PR

 

3.  This iis a right triangle where the right angle intercepts the diameter......the sum of the other two angles  = 90...so...

 

x +  54  =  90

Subtract 54 from both sides

x = 36

 

 

cool cool cool
