Answer:
A) 5 m
Explanation:
No ball is shown in the diagram. We assume that the distance of interest is the hypotenuse of a right triangle with legs 3 m and 4 m. Your knowledge of the 3-4-5 Pythagorean triple tells you the hypotenuse is 5 m.
___
If you actually need to use the Pythagorean theorem equation, you are looking for "c" where a=4 and b=3:
c² = a² + b²
c² = 4² + 3² = 16 +9 = 25
c = √25 = 5
The straight-line distance is 5 meters.
