Question

Find the Value of X. If your answer is not an integer, express it in simplest radical form.

Answer 1

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)
