0.05/(1 - 0.05) = 0.05/(0.95)
since we know that 0.05/1 = 0.05
0.05/(0.95) > 0.05
the best answer is C) 0.053

there is another way: hypotenuse: a^2 + b^2 = c^2 1) c = 21 c^2 = 441 441/2 + 441/2 = 441 sqrt(441/2) + sqrt(441/2) = 21 Area: sqrt(441/2) x sqrt(441/2) = 441/2 = 220.5 2) c = 19 c^2 = 361 361/2 + 361/2 = 361 sqrt(361/2) + sqrt(361/2) = 19 Area: sqrt(361/2) x sqrt(361/2) = 361/2 = 180.5 3) the diffe...
