In the right triangle ABC wherein AB is the hypotenuse, BC is the opposite and CA is the adjacent tanA=0.45. The approximate length of AB which is the hypotenuse is 22, Opposite (BC) is 9 and Adjacent (CA) is 20. You need to use pythagorean formula in getting the length of AB.
It the fourt day the total is 0.70 because Day one: .10 Day two: you double it so .20 Day three: you double it again so .40 Day four: you add .30 so .70 is the total
