The shadow is in same time therefore the angle will be equal and both the triangle will similar.
Let height(2) be x.
Therefore,
Height(1)/ Shadow(1) = height(2)/ shadow(2)
1.65/1.8 = x/5.4
(1.65×5.4)/ 1.8 = x
8.91/1.8 = x
X = 4.95
Therefore height of lamp post = 4.95m
If you satisfied mark it brainliest.
Let height(2) be x.
Therefore,
Height(1)/ Shadow(1) = height(2)/ shadow(2)
1.65/1.8 = x/5.4
(1.65×5.4)/ 1.8 = x
8.91/1.8 = x
X = 4.95
Therefore height of lamp post = 4.95m
If you satisfied mark it brainliest.
