Answer:
angle 3. ( x ) is 136°
angle 4 ( y ) is 44° !! 
Step-by-step explanation:
Let angle 3 be x and angle 4 be y 
Given, Angle 3 and angle 4 form a linear pair
x + y = 180 [ sum of linear pair angle is 180 ] ... ( i )
Also, The measure of Angle 3 is four more than three
The measure of Angle 3 is four more than threetimes the measure of angle 4.
x = 4 + 3y .... ( ii )
Putting value of x from ( ii ) in ( i )
4 + 3y + y = 180
4y = 176
y = 44 
Also, x + y = 180 => x = 180 - 44 = 136

Answer:
<h3>
  The width (side perpedicular to the barn):  
<u>x = 8 m</u></h3><h3>      The lenght (side parallel to the barn):  
<u>y = 16 m</u> </h3>
Step-by-step explanation:
x  - the width of the barn
She has 32 m of fencing so for the lenght remain (32-2x) m of fencing:
y = 32 - 2x
Area of the fencing:  A = x•y
A(x) = x•(32 - 2x)
A(x) = -2x² + 32x             ←  quadratic function
The maximum value of quadratic function occurs at:  
a = -2,  b = 32

32-2x = 32 - 2•8 = 16
