I don't understand the 2nd statement
LHS: Given that Alan and Ben received the same amount of money, Alan + Ben + Eddie = Alan + Alan + Eddie = 2(Alan) + Eddie
RHS: Given that Clara received $150 more than Alan, Clara = Alan + $150. In addition, as both Clara and Deon have the same amount of money (both have 90 degrees), Clara + Deon = [Alan + $150] + [Alan + $150] = 2[Alan + $150]
RHS: Given that Clara received $150 more than Alan, Clara = Alan + $150. In addition, as both Clara and Deon have the same amount of money (both have 90 degrees), Clara + Deon = [Alan + $150] + [Alan + $150] = 2[Alan + $150]
I don't understand the 2 units part
both clara and deon recieved 1 unit each, and 1 unit is actually a quarter of a circle(can see because of the right angle), therefore clara and deon adds up to 2 units. And that is half a circle, so 2 units is half a circle
