Respuesta :

Answer:

X = 108.

Step-by-step explanation:

Heights are equal, So equation will be,

[tex]4 + 3 \sqrt{x - 8} = 34[/tex]

So, solving the eq.

Subtract 4 from both sides ,

[tex]3 \sqrt{x - 8} = 30[/tex]

Divide 3 to both sides,

[tex] \sqrt{x - 8} = 10[/tex]

Squaring both sides,

[tex]x - 8 = 100[/tex]

Add 8 to both sides,

[tex]x = 108[/tex]
