Answer:
   40 degrees
Step-by-step explanation:
A triangle solver tool can find the angle easily. It is 39.8°, which rounds to 40°. Apps are available on some calculators, on the Internet, and for iOS and Android phones and tablets.
___
You may be expected to solve this using the Law of Cosines. If we name the sides ...
the law of cosines tells us the relationship is ...
   c² = a² + b² -2ab·cos(θ)
Then the angle is ...
   θ = arccos((a² +b² -c²)/(2ab)) = arccos((3.0625 +9 -4)/(2·1.75·3))
   = arccos(8.0625/10.5) ≈ 39.838° ≈ 40°
 
        
             
        
        
        
6 *20 = 120
8 *60 = 480
120 + 480 = 600 pounds total
 
        
             
        
        
        
Here we will use the trial and error method. 
- We will try putting different values of x.
<h3 /><h3>1st of all</h3><h3>x=1</h3>





<h2>Now,</h2><h3>x=2</h3>




<h2>Again,</h2><h3>x=3</h3>




<h3>☣Hence, The value of X as 3 satisfies the equation!</h3>
