Answer:
50
Step-by-step explanation:
Adding up 20, 30, 40, 50, 60, 70, 80, we get 350.  There are 7 numbers in this set, so divide this 350 by 7.  We obtain the mean, 350/7 = 50 (Answer B)
 
        
                    
             
        
        
        
CT=90°
BTA=90°
x=29
CT=37
TA=20
CA=57
Step-by-step explanation:
they say BT is an altitude ( or height) . Altitudes are perpendicular meaning that:
BTC =90°
BTA=90°
Therefore:
(3x+3)°=90°
3x=90-3
3x=87°
x=29
CT:
x+8
=29+8
=37
TA:
x-9
=29-9
=20
CA:
=CT+TA
=37+20
=57
 
        
             
        
        
        
m = np-6n
You just need to multiply both sides by n
