Df = g - 10
To solve for d, divide both sides by f.
df / f = (g - 10) / f
d = (g - 10) / f
I hope this explains it. 
        
             
        
        
        
1)inside the triangule is 180º .There are 3 angules, one with 120º, theta and 
angle ACB, lets call it x.
x + theta + 120 = 180
x + theta= 180-120
x + theta= 60
x= 60- theta 
angle ACB= 60- theta

Answer:
Step-by-step explanation:
x = 1.0
how:
we know that the Hyp of the small triangle is  
since we know that ,  then  
 = 1^2 + 1^2   by  Pythagoras theorem
 = 1^2 + 1^2   by  Pythagoras theorem
so each side is 1  :) 
 
        
             
        
        
        
w - width
2w - length
60 - perimeter
w + w + 2w + 2w = 6w - perimeter
The equation:
6w = 60    <em>divide both sides by 6</em>
w = 10 → 2w = 2 · 10 = 20
The area: A = width × length
A = (10)(20) = 200
<h3>Answer: The area of the garden is equal 200 square units.</h3>
