• # question_answer For what value of 'm' are the points (5,5), (m, 7) and (8,8) collinear? A)  6                                             B)  7 C)  8                             D)         5

The given points are collinear if the area of the triangle formed by the points is 0. $QA\bot AB$ $\text{PB}\bot \text{AB}$ $\Delta \text{QAO}=\text{245 c}{{\text{m}}^{\text{2}}}$ $\Delta \text{QAO}$ $\Delta \text{PBO}$ $\angle \text{QAO}=\angle \text{BPO},\text{ }\angle \text{AQO}=\angle \text{PBO}$
