Answer:
   14.25 yd^2
Step-by-step explanation:
The triangle area is given by the formula ...
   A = 1/2bh
Here, the base is 10 yd, and the height is 5 yd, so ...
   triangle area = (1/2)(10 yd)(5 yd) = (5 yd)^2 = 25 yd^2
__
The semicircle is half the area of a circle with radius 5 yd, so its area is ...
   semicircle area = (1/2)π(5 yd)^2 = 12.5π yd^2 ≈ 39.25 yd^2
__
The shaded region is the difference between these areas:
   shaded area = 39.25 yd^2 -25 yd^2 = 14.25 yd^2
 
        
             
        
        
        
B and a. it goes down about two lines and then has a very more steep incline
        
             
        
        
        
Idk about number 4 but I think the other ones are correct
 
        
             
        
        
        
Remark
There's a lot you don't know here. Are DE and GF parallel? Is B a right angle? You can't assume that it is. The safest way to proceed is to give x in terms of 58 and B. You might get an answer that gives you something like 32 but I don't think you can say that unless you are told somewhere that ABC is a right angle triangle with the right angle at B.
So what to do. 
<BAC = 58o                               That's because <BAC = <IAK They vertically opposite.
<ABC + <BAC + <ACB = 180o       All triangles have 180o
<ACB = 180 - 58 - <ABC                Solve for an unknown angle of a triangle.
<ACB = 122 - <ABC
x = <ACB                                       Vertically opposite angles.
x = 122 - <ABC                             Answer  It's 32 if ABC is a right angle.
