Question

two friends started from same point and walked 12m each, But in opposite direction then turned to his left and walked another 9m what is distance between them when they stop​

Answer 1

Answer:

21

Step-by-step explanation:

Answer 2

Answer:

30m

Step-by-step explanation:

According to the Pythagorean Theorem, the square of the hypotenuse side in a right-angled triangle equals the sum of the squares of the other two sides. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse. Due to its position opposite the 90° angle, the hypotenuse in this case is the longest side. When the positive integer sides of a right triangle (let's say sides a, b, and c) are squared, the result is an equation known as a Pythagorean triple. According to the Pythagoras theorem, the square of the hypotenuse of a triangle, which has a straight angle of 90 degrees, equals the sum of the squares of the other two sides. Here, AB stands for the base, AC for the height, and BC for the hypotenuse.

Hence 2 right angled triangles will be formed with sides as 12m and 9m.

$12^{2} +9^{2} \\=15^{2}$

Hence the Hypotenuse is 15m, Total Distance is 30m
