Answer:
Using the Pythagorean theorem:
c^2 = a^2 + b^2
where c is the length of the hypotenuse and a and b are the lengths of the other two sides.
Plugging in the given values:
c^2 = 48^2 + 14^2
c^2 = 2304 + 196
c^2 = 2500
Taking the square root of both sides:
c = √2500
c ≈ 50
Therefore, the length of the hypotenuse is about 50 cm (rounded to the nearest tenth).
