Let AB = height of the man And, CD = Height of the pole And, BD = AE = distance between the man and the pole = 24√3 metres In right triangle AEC; tan30° = CE/AE Or, 1√3 = CE/ (24√3) Or, CE = 24 metres So, height of the pole = CE + ED = CE + AB = 24 + 1.5 = 25.5 metres
If both the equations I and II given below are added, then find the product of roots of newly formed equation.
I: 3x2 + 9x + 5
A and B are the roots of equation x2 - 13x + k = 0. If A - B = 5, what is the value of k?
If the product of roots of equation x2 - 3(2p+4)x + (p2 - 24p + 145) = 0 is unity, then 'p' can take the values as
