Question

Find the missing side lengths

Answer 1

`\sin(45) = (o)/(h) \\ 0.7 = (x)/(18 √(2) ) \\ 0.7 * 18 √(2) = x \\ 0.7 * 25.45 = x \\ 17.8 = x`

`{x}^(2) + {y}^(2) =( 18 √(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`
