  6. Above written answer is wrong.Its right answer is 45 degree because- length of tower = length of its shadow so,perpendicular = base so, X = X We know that, tan theta = P/B = X/X = 1 and we know that the value of 1 is tan 45 degree.

  7. A small teiescope has an objective lens of focal length 144cm and eyepiece of focal length 6.0cm. What is the magnifying power of the telescope? What is the seperation between the objective and the eyepiece?

  8. It will be 0 degree, because length of shadow is hypotenuse. If length of hypotenuse is equal to the height of tower it means hypotenuse is perpendicular on ground. It means angle of elevation on the top will be 0 degree.

  9. if length of shadow of a tower is equal to height of tower then find the angle of elevation top of tower at the end point of shadow.
