Question

    Two pillars of equal height stand on either side of a

    roadway which is 150 m wide. At a point in the road between pillars, the elevations of the pillars are x° and y° so that tan  then the height of each pillar is:
    A 39m Correct Answer Incorrect Answer
    B 42m Correct Answer Incorrect Answer
    C 36m Correct Answer Incorrect Answer
    D 33m Correct Answer Incorrect Answer

    Solution

    Tan x ° =2/5, tan y°=3/5 Same height of pillars = h= 6=? Distance between pillar A and B= 15+10=25 ATQ given- 25=150 1 = 6 m Then height = 6 ×6 =36m
