A right triangle has an hypotenuse of 155 centimeters and a leg of 124 centimeters. Which of these is the length of the other leg?

A. 93 cm

B. 97 cm

C. 103 cm

D. 107 cm

It is the square root of 155^2-124^2 according to Pythagorean's theorem, which is equal to 97, so it is B.

For this problem, we use the Pythagorean theorem which is a relationship for the side length of a right triangle. It is expressed as:

c² = a² + b²

where c is the hypotenuse of the triangle.

155² = 124² + b²

b² = 155² - 124²

b = 93 cm

Therefore, the correct answer is option A.
