Question

In the triangle shown below, what is the approximate value of x?2513O A. 19 unitsOB. 13 unitsO C. 29.07 unitsO D. 22.52 units

Answer 1

The legs of the right triangle are 9 ft (a) and 12 ft (b). Calling c to the hypotenuse and using Pythagorean theorem, we get:

c² = a² + b²

c² = 9² + 12²

c² = 81 + 144

c² = 225

c = √225

c = 15 ft
