    1.6 + BC =√3 BC
    √3BC - 1BC = 1.6
    (Taking BC common),,
    BC(√3-1) = 1.6
    BC = 1.6/√3-1
    (Rationalise),,
    BC= 1.6/√3-1×√3+1/√3+1
    1.6(√3+1)/(√3)²-(1)² = 1.6(√3+1)/3-1
    =1.6 √3+1)/2
    =0.8(√3+1)m. {ANS}
    •< Hence the height of pedestal= 0.8(√3+1)m.
    Those who are saying that sir's answer is wrong, actually it is not...Just he has use another method..
    So you can solve this question by above method also that I had already mentioned.👍

    For those wondering about the answer in book , which is 0.8(√3+1) that is correct but also this answer is correct because:-
    8/10 * (1.73+1) = 4/5 *273/125 which is equal to 2.18

    • @misbah3041
      @misbah3041 2 года назад +2

      The original value of root 3 is 1.7320508076, but while solving we only consider two numbers after the decimal so that it is easy to calculate. You can even use the full value of root 3 but it is not necessary. You can use up to first 3 digit after the decimal for your convenience.

      *Hi
      《Note: like this and sir give a ❤ 》
      Nothing big issues that one is also correct but if you want that answer of ncert maths text book so you can do as follows
      After, 1.6+BC = BC root 3
      BC(root - 1) = 1.6
      BC =1.6/root 3 - 1
      After rationalise 1.6/root 3 - 1
      You got, 1.6(root 3 + 1)
      -----------------------
      2
      Your answer: 0.8(root 3 + 1)*
