Answer:

given \: that \:first \: number \: is \: 45 + x  \\given \: sum \: of \: two \: numbers \: is \: 90 \\  then \: the \: second \: number \: is \: 90 - (45 + x) \\  = 45 - x \\ given \: product \: of \: two \: numbers \: is \: 2009 \\ therefore  \\ (45 + x)(45 - x) = 2009 \\ (x+ y)(x - y) =  {x}^{2} -  {y}^{2}   \\  {45}^{2}  -  {x}^{2}  = 2009 \\ 2025 -  {x}^{2}  = 2009 \\ 2025 - 2009 =  {x}^{2}  \\ 16 =  {x}^{2}  \\ x =  +4 \: or \:  - 4 \\ the \: two \: numbers \: are \: 45 - 4 \: and \: 45 + 4\\  i.e \: 41 \: and \: 49
