First one....ABD  =  90°

 

Second one :  DQM  =  180  - 90  - 50  =  40°

 

I answered the 3rd one on your other post

 

Fourth one

 

18 ( n + 1)  =  9 (n + 7)    divide both sides by  9

 

2(n + 1)  =  n + 7     simplify

 

2n + 2  =  n + 7    subtract n , 2  from  both sides

 

n  = 5

 

 

Fifth one  ..the last statement is correct

 

 

cool cool cool
