Using Pythagoras's theorem, we can get that 60 inches is the hypotenuse and 52 inches is one of the legs. 60^2 - 52^2 = b^2, where b is the leg that we are trying to find, aka the length of the shadow. We find that b^2 = 896. The square root of 896 is closest to 30 inches, therefore the answer is A) 30 inches
You would have to do 18.18 times 10, keep that answer. then you do 18.18 plus 2.18 and get the answer to that and add it together from the answer from the first question (18.18 times 10)
