Answer:

x = 49

Step-by-step explanation:

The third side of the largest of the inner triangles:

= [tex]\sqrt{(7\sqrt{(33)^{2} }- (33)^{2}[/tex]

=[tex]\sqrt{528} =\sqrt{(16)(33)} =4\sqrt{33}[/tex]

The side that continues next to 33: x -33

Applying similarity property on right triangles:

[tex]\frac{33}{4\sqrt{33} } =\frac{4\sqrt{33} }{x-33}[/tex]

[tex](33)(x-33)=(4\sqrt{33} )^{2}[/tex]

[tex]33x-1089=528[/tex]

[tex]33x=528+1089[/tex]

[tex]x=\frac{528+1089}{33} =49[/tex]

Hope this helps
