Find the measure of each angle.

  

A line segment divides a right angle into two separate angles. One angle is labeled "5x plus 7" and the other angle is labeled "3 x plus 3". 5x + 7

 

3x + 3

 

 

5x+7= ___degrees°

3x+3= ___ degrees

The angles sum to 90.....so....

 

[3x + 3 ] + [ 5x + 7 ]   =  90

 

8x + 10  = 90         subtract 10 from both sides

 

8x  = 80               divide both sides by 8

 

x  = 10

 

So   

 

5(10) + 7   =  57°

3(10) + 3  =   33°
