A right triangle has an hypotenuse of 155 centimeters and a leg of 124 centimeters. Which of these is the length of the other le
g ?
A. 93 cm
B. 97 cm
C.103 cm
D. 107 cm
2 answers:
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.
It is the square root of 155^2-124^2 according to Pythagorean's theorem, which is equal to 97, so it is B.
