Answer:
18√2 or 25.46 inches.
Step-by-step explanation:
- the hypotenuse of a triangle is legs times √2 or L√2.
- we get
[tex]l = 18 \\ hyp = l \sqrt{2} \\ 18 \sqrt{2} \\ 25.46[/tex]
using pythagorean theorem we get:
[tex] {c}^{2} = {a}^{2} + {b}^{2} \\ {c}^{2} = {18}^{2} + {18}^{2} \\ {c}^{2} = 324 + 324 \\ \sqrt{ {c}^{2} } = \sqrt{648} \\ c = 25.46[/tex]
therefore, the length of the tie is 25.46 inches.
