Question

if the square of the hypoteneus of an isoseles right angled triangle is 242sq. cm , find the length of each of the other two sides of a triangle​

Answer 1

x² + x² = 242 ( Pythagoreas theorem)

2x² = 242

x² = 141

x = √ 141

Answer 2

answer

121

step by step

$ac ^{2} = ab {}^ {2} + bc {}^{2} \\ 242 = x + x \\ 242 = 2x \\ 242 \div 2 = x \\ 121 = x \\ x = 121$
