I think you need to add them all up first or do the 90 degree

Answer:

m∠R =​ 22.62°

Step-by-step explanation:

cos R= 12/13 = 0.92307  

cos-1 (0.92307) = 22.6208962497961

                          = 22.62

sin R= 5/13 =  0.38461

sin-1(0.38461) = 22.6195307230661

                       = 22.62

tan R = 5/12 = 0.41666

tan-1(0.41666) = 22.6195394801202

                        = 22.62

Round only your final answer to the nearest hundredth

when you round all of them to there nearest hundredth you get  

22.62°
