during a flooded control field work a hydraulic engineer walks a distance of $540$m at bearing of $25$ degrees from a flooded house to a flooded market. then from a flooded market the engineer walks $850$m at a bearing of $115$ degrees to a drainage pour point. it is then proposed that a straight drainage channel be constructed between the flooded house and the drainage pour point from the flooded house.

a$)$ calculate the bearing of the drainage pour point from the flooded house
