A) \[\sqrt{pq}\]
B) \[\frac{2pq}{p+q}\]
C) \[\frac{(p+q)}{2}\]
D) \[\frac{1}{2}(p-q)\]
Correct Answer: C
Solution :
In \[\Delta \,\,ADC\] M and N are mid-point of AD and BC \[\therefore \,\,\,MO=\frac{q}{2}\] (mid-point theorem) and \[ON=\frac{P}{2}\] \[\therefore \,\,\,\,\,MO+ON=MN=\frac{p}{2}+\frac{q}{2}=\underline{\frac{\mathbf{1}}{\mathbf{2}}\mathbf{(p+q)}}\]You need to login to perform this action.
