Answer:

The answer to your question is 19.4

Step-by-step explanation:

Data

Right triangle

hypotenuse = 40

adjacent side = b

opposite side = 35

Process

1.- To solve this problem use the Pythagorean theorem

                         c² = a² + b²

- Substitution

                         40² = 35² + b²

- Solve for b²

                            b² = 40² - 35²

                            b² = 1600 - 1225

                            b² = 375

- Result

                            b² = 19.36 ≈ 19.4
