Answer 1

Answer:

x ≈ 2.73

Step-by-step explanation:

The two triangles are scaled.

So...

$\frac{10}{11} = \frac{x}{3}\\\\30 = 11z\\\\x = 30/11$

x = 2.727272..... ≈ 2.73

Answer 2

$\\ \sf{:}\longrightarrow \dfrac{AB}{BC}=\dfrac{AD}{ED}$

$\\ \sf{:}\longrightarrow \dfrac{10}{x}=\dfrac{10+1}{3}$

$\\ \sf{:}\longrightarrow \dfrac{10}{x}=\dfrac{11}{3}$

$\\ \sf{:}\longrightarrow 11x=30$

$\\ \sf{:}\longrightarrow x\approx 3$
