Answer:
2 m
Step-by-step explanation:
Here the area and the lengths of the two parallel sides of this trapezoid are given:
A = 7m^2, b1 = 3 m and b2 = 4 m.  What's missing is the width of the trapezoid.
First we write out the formula for the area of a trapezoid:
        b1 + b2
A = --------------- * w, where w represents the width of the figure.
              2
We need to solve this for the width, w.  Multiplying both sides of the above equation by 
      2
------------
 b1 + b2
results in
  2A
------------ = w
 b1 + b2
Substituting 7 m^2 for A, 3 m for b1 and 4 m for b2 results in
         2(7 m^2)           14 m^2
w = ------------------ = ---------------- = 2 m
         (3 + 4) m             7 m
The missing dimension is the width of the figure.  This width is 2 m.
 
        
             
        
        
        
Answer:
x = 110°
Step-by-step explanation:
The sum of the interior angles in a quadrilateral is 360°. This means:
x + x + x - 30 + 1/2x + 5 = 360° - we can simplify this
3 1/2x - 25 = 360° - now add 25 to both sides
3 1/2x = 385 - finally divide both sides by 3 1/2
x = 385 ÷ 3.5 = 110
x = 110°
Hope this helps!
