Answer:

2:A number is greater than 17.2

Step-by-step explanation:

the ">" in the inequality represents is greater

so the m> means m is greater than... and then the 17.2 means m is greater than 17.2. The way I learnt it was to imagine the ">" sign is like a crocodile, it wants the bigger number. So the ">" being towards the "m" shows that m is the bigger number.

Answer:

x=\boxed{6.6}

\overline{\sf DE}=\boxed{13.2}\:\:\sf units

Step-by-step explanation:

<u>Geometric Mean Theorem - Altitude Rule</u>

The <u>altitude</u> drawn from the vertex of the right angle perpendicular to the hypotenuse separates the <u>hypotenuse</u> into <u>two segments</u>.  The ratio of one segment to the altitude is equal to the ratio of the altitude to the other segment:

\sf \dfrac{segment\:1}{altitude}=\dfrac{altitude}{segment\:2}

From inspection of the given diagram:

  • altitude = FD = 9
  • segment 1 = CD = 5
  • segment 2 = DE = 2x+3

\begin{aligned}\sf \dfrac{segment\:1}{altitude} & = \sf \dfrac{altitude}{segment\:2}\\\\\implies \dfrac{5}{9} & = \dfrac{9}{2x+3}\\\\5(2x+3) & = 81\\\\10x+15 & = 81\\\\10x & = 66\\\\ \implies x & = 6.6\end{aligned}

Substitute the found value of x into the expression for DE:

\begin{aligned}\sf \overline{DE} & = 2x+3\\\implies \sf \overline{DE} & = 2(6.6)+3\\& = 13.2+3\\& =16.2\:\: \sf units\end{aligned}
