Answer:
10m
Step-by-step explanation:
<u>Perimeter</u> means adding up all of the sides of a shape.
One property of a square is that <u>all lengths of a square are the same</u>.
We also know squares have <u>4 sides</u>.
<u />
Lets set up an expression to solve the length for each side with variable S representing the length of a side:
4 * S = 40
Divide each side by 4:
S = 10
Therefore, each side of the square has a length 10m

Answer:
A: x = 20
Step-by-step explanation:
 
        
                    
             
        
        
        
As shown in the image, we have a 30 degree angle and x, which is what we want. By doing tan30, we can find x, so tan30=x/70 and 70*tan30=x= 70*sqrt(3)/3. 120-x=height of first tower = 120-(70*sqrt(3)/3) = roughly 79.59
