问题 In the figure above, what is the value of 2s-r?
选项 A、60
B、70
C、100
D、140
E、220
答案E
解析 Since 4r and 5r form a straight line, which is 180 degrees, 4r+5r=180. When we simplify that to 9r=180, we can solve to get r=20. Therefore 5r=100, and s-20=100. So we can tell that s=120. Using those numbers, the equation 2s-r becomes 2(120)-20, which equals 220.
