(03.02 LC)

A triangle has squares on its three sides as shown below. What is the value of x?

Three squares having side lengths 9 cm, x cm, and 12 cm joining to form right triangle at the centre

12 inches
15 inches
108 inches
144 inches

Answer 1

15
as
15²=12²+9²(using Pythagoras theorem)
or
225= 144+81
225=225
(the Pythagorean theorem, also known as Pythagoras's theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. )
