Answer 1

Answer:

17.5

Step-by-step explanation:

$15^{2}+9^{2}= 306$

$\sqrt{306} = 17.5$

Answer 2

Answer:

x ≈ 17.5

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

x² = 9² + 15² = 81 + 225 = 306 ( take the square root of both sides )

x = $\sqrt{306}$ ≈ 17.5 ( to the nearest tenth )
