Answer:
D
Step-by-step explanation:
Remember that the sum of the interior angles of a triangle will always total 180. 
Therefore: 

Let’s solve for <em>x: </em>
Combine LIke Terms: 

Add: 

Subtract 80 from both sides: 

Divide both sides by 25: 

Therefore, the value of <em>x </em>is 4. 
Now, to find A, we can substitute it for A. 
A is measured by: 

Substitute 4 for <em>x</em> and evaluate: 

Hence, our answer is D. 
 
        
             
        
        
        
The equation that you are looking for is y = -2x + 3
        
             
        
        
        
A standard deck of cards has 52 cards. Half of the deck has red cards and half has black cards. So the first probability would be 26/52, or 1/2 (simplified, it's half the deck).
Then you put the card back and choose a 3. There are 4 cards with the number 3 in the deck. So it's 4/52.
Then you multiply both the probabilities
26/52 x 4/52 = 

 = 1/26
 
        
        
        
Answer:
55.8
Step-by-step explanation:
44 ^ 2 = 1936
b ^ 2 = 55 .8 ^ 2
51 ^ 2 = 2601
