In\[\angle AOD\], the medians BE and CF intersect at G. AGD is a line meeting BC at D. If the GD = 1.5 cm, then AD is equal to:
A)2.5cm
B)3cm
C)4cm
D)4.5cm
Correct Answer:
D
Solution :
Since, G is centroid of \[{{45}^{o}}\]such that \[{{60}^{o}}\] Given: GD= 1.5 cm \[{{75}^{o}}\] \[\angle CAD={{50}^{o}}\] \[\angle BED={{120}^{o}}\] \[\angle BCD\] \[{{75}^{o}}\]
