Recall that a dilation with center (0, 0) and scale factor 
 maps 
 onto 
.
Now, triangle ADE is formed by

Whereas triangle ABC is formed by

In other words, the coordinates of B and C can be obtained by multiplying by 2 the coordinates of D and E.
This means that you get ABC from ADE by dilating with center (0,0) and scale factor 2.
 
        
                    
             
        
        
        
The total prize money is 200+100 which is 300
There is 100 tickets sold for $5 each so the people selling the tickets earn $500 and use $300 for prize money.
The expected value of 1 ticket is $5.00

Answer: 135°
Step-by-step explanation:
The sum of the angles in a pentagon is equal to 540°, and the sum of the first four angles is 405°.
70 + 90 + 100 + 145 = 405
540 - 405 = 135
