Answer:
YZ ≈ 13.7
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is
YZ² + XY² = XZ²
YZ² + 10² = 17²
YZ² + 100 = 289 ( subtract 100 from both sides )
YZ² = 189 ( take the square root of both sides )
YZ = [tex]\sqrt{189}[/tex] ≈ 13.7 ( to the nearest tenth )
