sin(β)=Opposite/Hypotenuse

Therefore:

sin(54)=x/10

Therefore:

x=10*sin(54)

x=8.1 (To the nearest tenth)

Answer: $\bold{\sqrt{2}-15\sqrt{3}}$

<u>Step-by-step explanation:</u>

$.\quad \sqrt{128}-5\sqrt{27}+2\sqrt{32}-3\sqrt{75}\\\\=\sqrt{\underline{2\cdot 2}\cdot \underline{2\cdot 2}\cdot \underline{2\cdot 2}\cdot 2}-5\sqrt{\underline{3\cdot 3}\cdot 3}+2\sqrt{\underline{2\cdot 2}\cdot \underline{2\cdot 2}\cdot 2}-3\sqrt{2\cdot \underline{5\cdot 5}}\\\\=2\cdot 2\cdot 2\sqrt{2}-3\cdot 5\sqrt{3}+2\cdot 2\cdot 2\sqrt{2}-5\cdot 3\sqrt{2}\\\\=8\sqrt{2}-15\sqrt{3}+8\sqrt{2}-15\sqrt{2}\\\\=\sqrt{2}-15\sqrt{3}$
