Answer:
The statue is 12 meters taller than Anakka.
Step-by-step explanation:
Use the Pythagorean Theorem which is a^2+b^2=c^2. The length is b. You know that the statue in Dover Park is 16 miles away so that is b. You know that the hypotenuse is 20 so that means the equation will be a^2+16^2=20^2. Simplify this to get a^2+256=400. Simplify this to get a^2=144. Divide each side by squared so that means a=square root of 144 which is equal to 12. Therefore, the statues is 12 meters taller than Anakka.
