Answer:
1 minute and 8 seconds or 1:08
Step-by-step explanation:
by subtracting both at starting with 9:17-8:49 you will get a uneven decimal than you gonna have to give as much 60 seconds you can get out of it the 60 seconds equals a minute 
 
        
             
        
        
        
The value of ∠X = 58.11°, If ΔWXY, the measure of ∠Y=90°, XW = 53, YX = 28, and WY = 45.
Step-by-step explanation:
The given is, 
                    In ΔWXY, ∠Y=90°
                         XW = 53
                          YX = 28
                         WY = 45
Step:1
              Ref the attachment,
              Given triangle XWY is right angled triangle.
              Trigonometric ratio's,
                                ∅
 ∅   
     
              For the given attachment, the trigonometric ratio becomes,
                                ∅
 ∅   .....................................(1)
.....................................(1)
              Let, ∠X = ∅
              Where, XY = 28
                          XW =  53
              Equation (1) becomes,
                                   ∅
 ∅  
                                   ∅ = 0.5283
 ∅ = 0.5283
                                         ∅ =  (0.5283)
 (0.5283)
                                         ∅ = 58.109°
Result:
           The value of ∠X = 58.11°, If ΔWXY, the measure of ∠Y=90°, XW = 53, YX = 28, and WY = 45.
