The boy walked 550 m east from the house, then turned north and walked 480 m at what distance the boy was in meters from the house.

To solve this problem, we introduce the conditional variable “X”, through which we denote the distance from the house, at which the boy found himself at the end of his journey.
Then, applying the Pythagorean theorem and based on the data of the problem, we will compose the following equation: X x X = 550 x 550 + 480 x 480.
Solving this equation, we get X equal to 730 meters.
Answer: at the end of the path, the boy was 730 meters from the house.
