For this case what we should do is use the Pythagorean theorem. We have then: PQ ^ 2 = 15 ^ 2 + 19 ^ 2 Clearing we have: PQ = root (15 ^ 2 + 19 ^ 2) Answer: The expression used to find PQ is given by: PQ = root (15 ^ 2 + 19 ^ 2) option C
We have to use the Pythagorean theorem. So it will be: PQ ^ 2 = 15 ^ 2 + 19 ^ 2 PQ = root (15 ^ 2 + 19 ^ 2) So the expression used to find PQ is given by: PQ = root (15 ^ 2 + 19 ^ 2)
