a. 5.2
b. 3
c. 7.3
d. 9

The answer to your question is letter D

Step-by-step explanation:

Data

hypotenuse = h = 15 ft

adjacent leg = a = 12 ft

opposite leg = b = ?

Formula

We must use the Pythagorean theorem to solve this problem

                      h² = a² + b²

Substitution

Solve for b

                     b² = h² - a²

                     b² = 15² - 12²

                     b² = 225 - 144

                     b² = 81

Result

                     b = 9 ft                    

b
