QT= √25^2-7^2=24
RT= √51^2-24^2=45
RS=RT-ST=45-7=38
RS=38
Hope it helps^
Give a brainliest please:-)

In mathematics, the Pythagorean theorem, or Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.

so QT² = 25² - ST²

QT = 24

RT² = 51² -25²

RT = 45

RS = 45 - 7 = 38 cm
