An airplane flies from City A in a straight line to City B, which is 110 kilometers north and 155 kilometers west of City A. How far does the olane fly? (Round your answer to the nearest kilometer.) X km LARPCALC10M 1.1.054. A line segment has \( \left(x_{1}, y_{1}\right) \) as one endpoint and \( \left(x_{m}, y_{m}\right) \) as its midpoint. Find the other endpoint \( \left(x_{2}, y_{2}\right) \) of the line segment in terms of \( x_{1}, y_{1}, x_{m} \) and \( y_{m} \). Use the result to find the coordinates of the endpoint \( \left(x_{2}, y_{2}\right) \) of each line segment with the given endpoint \( \left(x_{1}, y_{1}\right) \) and endpoint \( \left(x_{m}, y_{m}\right) \). (a) \( \left(x_{1}, y_{1}\right)=(1,-6),\left(x_{m}, y_{m}\right)=(7,-1) \) \( \left(x_{2}, y_{2}\right)=(\quad x) \) (b) \( \left(x_{1}, y_{1}\right)=(-4,17),\left(x_{m}, y_{m}\right)=(9,2) \) \[ \left(x_{2}, y_{2}\right)=(\quad x) \]
