Answer:

17.54

Explanation:

Use the pythagorean theorem, c would be 18 due to it being the diagonal side.

4^2+x^2=18^2

16+x^2=324

324-16=308

take the square root of 308 and you'll get the answer

Answer:

x = 17.55 (rounded to nearest hundredth)

Explanation:

Slant length =
$\sqrt{a^(2)+b^(2)}$

We just need to put in the values that we know first.

18 =
$\sqrt{4^(2)+x^(2)}$

18 =
$\sqrt{16+x^(2) }$

18² = 16 + x²

324 = 16 + x²

x² = 324 - 16

= 308

x =
√(308)

x = 17.55 (rounded to nearest hundredth)
