Chandler · Answer 1

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
