Answer:
R = 90
Step-by-step explanation:
Triangles will always equal 180 degrees. If you add 61 + 29 = 90. If two of the three angles already equal 90 degrees, then you would subtract 180 - 90. Therefore, the remaining angle would have to be 90 degrees. 
 
        
             
        
        
        
Regular pay:
45x40x17=30,600
Overtime:
45x6x17x1.5=2142
Total payroll= 30,600+2142=32,742
Total overtime/total payroll * 100 =
2142/32,742 *100 = 6.5%
