Question 463453


 Question: Find the Complement of the angle measure

   ANGLE MEASURE 
1.)  37 degrees              
2.)  48 degrees              
3.)  20 degrees              
4.)  x degrees               
5.)  (2x+ 10) degrees        

  EQUATION
1.)  37+c=90             
2.)  48+c=90             
3.)  20+c=90             
4.)  x+c=90  
5.)  (2x+ 10)=90


   COMPLEMENT
1.) 53 degrees
2.) 42 degrees
3.) 70 degrees
4.) __c=90-x ___-------x=0 because it should be added to 90 to get 90
5.) ___2x+ 10=90 _____2x=90-10---2x=80......x=40
                        
In equation number 1, I just transposed 37 to the right and then I subtract 37 to 90 that's how I got 53 degrees as the complement of the angle measure. But I just couldn't figure out question number 4 and number 5.
