A technician has to repair a light on a pole of height 10 m. She needs to reach a point 2 m below the top of the pole to undertake the repair work. The length of the ramp that she should use which, when inclined at an angle of 30∘ to the horizontal, would enable her to reach the required position, is______ m.
(You may take √ = 1.73)
Let BD be the height of the pole. And A is the point where she has to do the repair work.
So, distance of the point she should reach = AB = 10 - 2 = 8 m
In the given right-angled triangle,
Hence, length of the Ramp AC = 2 × 8 = 16m
