Answer:
Step-by-step explanation:
<h3>7) The lengths of the tangent from an external point to a circle are  equal.</h3>
       2x - 1 = x + 10
            2x = x + 10 + 1
            2x = x + 11
       2x -x  = 11
              
 8) Radius : XC
     Chord: CB
    Diameter : AB
   Name of the circle: X    {a circle is named by its center}
 
        
             
        
        
        
Answer:
18 boys
Step-by-step explanation:
boys/girls = 3/11 = b/66
3/11 = b/66
11b = 3 × 66
b = 3 × 6
b = 18
There are 18 boys.
 
        
             
        
        
        
I don’t know if I’m completely correct but the interior of a pentagon is 540 degrees so add all of them up. Then subtract 540- all of them added up and that should be the answer
        
             
        
        
        
For this case we must express the number "423" in a radical way.
We have to, we can rewrite it as:

So, we have to:

By definition of properties of powers and roots we have:
![\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}](https://tex.z-dn.net/?f=%5Csqrt%20%5Bn%5D%20%7Ba%20%5E%20m%7D%20%3D%20a%20%5E%20%7B%5Cfrac%20%7Bm%7D%20%7Bn%7D%7D)
So:
