In a right triangle, a = 14.2 cm and b = 13.9 cm. Find c. Round to the
nearest tenth.

Applying the Pythagorean theorem, the value of c in the right triangle, to the nearest tenth is: B. c = 19.9 cm
The Pythagorean theorem is used to find any side of a right triangle. If c is the hypotenuse, and a and b are the legs, the Pythagorean theorem states that, c = √(a² + b²).
Given:
Thus:
c = √(14.2² + 13.9²)
c = 19.9 cm.
