For each question we must apply the Pythagorean theorem and clear the value of x. question 5 x = root (14 ^ 2 + 16 ^ 2) x = root (452) x = 2raiz (113) question 6 x = root (8 ^ 2 + 15 ^ 2) x = 17 question 7 x = root (12 ^ 2 + 12 ^ 2) x = root (2 * (12 ^ 2)) x = 12raiz (2) question 8 x = root (18 ^ 2 - 9 ^ 2) x = root (243) x = 9raiz (3)
