Question

3. Have you ever thought how after construction a site engineer checks walls are perpendicular to each other. Pythagorean Theorem is used for the same. A point C is marked at a distance of 30 cm far from the wall and a point A is marked at a distance of 40 cm from the floor. If the measurement of AC is 50 cm, the wall is perpendicular (as 30-40-50 is a Pythagorean Triplet), otherwise not. If we keep BC as 20 cm and AB as 99 cm, find the length of AC if the walls are perpendicular.
