Answer:

Step-by-step explanation:
Given

Required
Probability of two people having dog
First, we have to convert the given parameter to decimal


Let P(Dogs) represent the required probability;
This is calculated as thus;
<em>P(Dogs) = Probability of first person having a dog * Probability of second person having a dog</em>
<em />




<em>Hence, the probability of 2 people having a dog is </em> <em />
<em />
 
        
             
        
        
        
Wow. ok, I didn't expect this to be a triangle question.
You would need to use cosine to solve this.
Side 1: 160<span>     opposite angle: </span>58°
<span>Side 2: </span>180<span>     opposite angle: </span>73°
<span>Side 3: </span>140<span>     opposite angle: </span><span>48°</span>
        
                    
             
        
        
        
Answer:
a = 2 
Step-by-step explanation:
Given
 a =
 a = 
Multiply both sides by 9 ( the LCM of 3 and 9 ) to clear the fractions
3a = 7 ( divide both sides by 3 )
a =  = 2
 = 2 
 
        
                    
             
        
        
        
Answer:
y is B. 82 degrees (and for extra, x is 54 degrees)
Step-by-step explanation:
The angles shown are complementary, which means they equal 180 degrees. Subtract 73 from 180 to get 107 degrees for the other angle in this set. After that subtract 25 from 107 to get y, which is 82 degrees.
(For x, just subtract 19 from 73 to get 54 degrees.)
 
        
             
        
        
        
U divide the shapes into two, you get a square and triangle. to find area you do b•h, so, 9•6=54,,, now u find area for the triangle wish is b•h/2,, 6•3/2= 9,,, the total area is 54+9=63
