11 and 12.
the square of 11 is 121 and the square of 12 is 144 and because 140 is between 121 and 144, 11 and 12 are the correct answer.
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)
