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

Answer:
sqrt( 17^2+ 25^2)
Step-by-step explanation:
Since this is a right triangle, we can use Pythagorean theorem
a^2+b^2 = c^2 where a and b are the sides and c is the hypotenuse
Taking the square root of each side
sqrt(a^2+b^2) = QR
sqrt( 17^2+ 25^2) = QR
Answer:
[tex] \small \sf A. \sqrt{25 {}^{2} + 17 {}^{2} } [/tex]
Step-by-step explanation:
Using pythagoras theorem
( Base) ² + ( Perpendicular) ² = (Hypotenuse) ²
( QS)² + ( RS)² = (OR )²
( 25 )² + ( 5 )² = OR²
Taking square root of each side.
[tex] \sqrt{25 {}^{2} + 17 {}^{2} } = \sqrt{OR}[/tex]
[tex] \sqrt{25 {}^{2} + 17 {}^{2} } = {OR}[/tex]
