Find the missing side lengths
sesenic [268]

Answer:

\sin(45)  =  \frac{o}{h}  \\ 0.7 =  \frac{x}{18 \sqrt{2} }  \\ 0.7 \times 18 \sqrt{2}  = x \\ 0.7 \times 25.45 = x \\ 17.8 = x

{x}^{2}  +  {y}^{2}  =( 18 \sqrt{2}  ) ^{2} \\  {17.8}^{2}  +  {y}^{2}  = 648 \\ 316.84 +  {y}^{2}  = 648 \\  {y}^{2}  = 648 - 316.84 \\  {y}^{2}  = 331.16 \\ y = 18.19
