Answer:
x = 19°
Step-by-step explanation:
we can see from observation that 22° and (3x+11)° are complementary. I.e they add up to 90°
hence
22 + (3x+11) = 90
22 + 3x+11 = 90
33 + 3x = 90   (divide both sides by 3)
11 + x = 30  (subtract 11 from both sides)
x = 30 - 11 
x = 19°
 
        
                    
             
        
        
        
Answer:
20.2 miles
Step-by-step explanation:
This can be described by the three sides of a right angled triangle. Let the distance of the glider to the airport be represented by x, applying the Pythagoras theorem:
 =
 =  +
 + 
 =
 =  +
 + 
576 =  + 169
 + 169
 = 576 - 169
 = 576 - 169
    = 407
x = 
   = 20.1742
x = 20.2 miles
The glider has to fly 20.2 miles to return to the airport.

The first thing you should do is solve the equation yourself.
1) Distribute the 2.  
6x + 4 = 2x – 16
2) Next, you'll want to get the x's on one side. So add -2x to both sides.
6x + 4 + -2x = 2x + -2x - 16
4x + 4 = -16
3) Now subtract 4 from both sides
4x + 4 – 4 = -16 – 4
4x = -12
4) Finally, divide both sides by 4
4x/4 = -12/4
x = –3
