Question

Which expression gives the length of pq in the triangle shown below?

Answer 1

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)


So the answer would be letter C.

Answer 2

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
