What are the correct ways to name this ray?

• $\overrightarrow{AB}$

• $$\overrightarrow{CA}

• $\overrightarrow{BC}$

• $\overrightarrow{AC}$

 $\angle ABC$  is a right angle.  The ratio of the measures of  $\angle ABD$  and  $\angle DBC$  is 7 to 8.  Find the  $m\angle ABD$  

•  $45\degree$  

•  $48\degree$  

•  $42\degree$  

•  $12\degree$  

 $\overrightarrow{TZ}$  bisects  $\angle XTY$  .  If  $m\angle XTZ=12x-13$  and  $m\angle ZTY=5x+15$  , what is the value of x?

 $\angle TRS\ is\ a\ straight\ angle.$  

 $\angle TRX\ is\ a\ right\ angle.$  
 $m\angle TRS=2x+5y$  
 $m\angle XRS=3x+3y$ 

Solve for x and y.  Write you answer as an ordered pair!
