A monster stands at 80 inches tall and casts a shadow that is 148 inches. What is angle of elevation from the end of the shadow to the top of the monsters head.

The formula is known as the Pythagorean theorem. a^2+b^2=c^2.

First we need to find a, either side will work for a or b, but let the height of the monster represent a (80). We need to find 80^2. We get 6400, now we work on b to find c^2. 148^2 is equal to 21,904. We need to add these numbers to find c. 6400+21904=28,304, or c^2. You are trying to find c, so we find the square root of c^2 to find c. The square root of 28304 is about 168.23. There is your answer, 168.23
