The defenition of a rectangle is that it has 4 angles that measure 90 degrees
ther are infinite legnths and inifinite numbers
intinite side legnths so infinite number of unique rectangles
        
                    
             
        
        
        
Answer:
x=-4
Step-by-step explanation:
-2x+18-1x+4=34
step 1 combine like terms 
-2x+-1x=-3x
18+4=22
-3x+22=34
step 2 subtract each side by 22
-3x=12
step 3 divide each side by -3
x=-4
hope this helps (:

The area of the semicircle
First, we calculate the hypotenuse (h) of the triangle
Considering only the triangle, we have:
 --- cosine formula
 --- cosine formula
Make h the subject



The area of the semicircle is then calculated as:

This gives:
