Answer:
the pair of angles of SUR and NUR are complimentary so the measure of NUR  is 49 degrees. TUR is equivalent to RUQ
Step-by-step explanation:
Complimentary means they add up to 90 degrees. so 90-41= 49 so the angle measure of NUR is 90 degrees.
 
        
                    
             
        
        
        
Ascending order :-
10.5 , 11 , 11.5 , 14.5 , 17 , 17 , 18 , 19
Median,
={(n/2)th + (n/2 +1)th}/2 
={(4)th + (5)th}/2 
=(31.5)/2 
=15.75
I.Q.R.,
Median of lower half,
={(n/2)th + (n/2 +1)th}/2 
={(2)th + (3)th}/2 
=(22.5)/2 
= 11.25
Median of upper half,
={(n/2)th + (n/2 +1)th}/2 
={(2)th + (3)th}/2 
=35/2
=17.5
I.Q.R. = 17.5 - 11.25 = 6.25
