If the height of a tower is given by the minimum of `x+1/x`,x>0, then its distance from the point of observation, if the angle of elevation of its top is `45^@` is: a.)1 unit b.) 2 unit c.)3 unit d.) 4 unit

If the height of a tower is given by the minimum of x+(1)/(x),x>0, then its distance frrom the point of observation,if the angle of elevation of its top is 45^(@) if the angle of c.)3unit d.) 4 unit

If the height of a tower and the distance of the point of observation from its foot, both are increased by 10% , then the angle of elevation of its top remains unchanged.

If the height of a tower and the distance of the point of observation from its foot, both are increased by 10% , then the angle of elevation of its top remains unchanged.

From a point on the ground,the angle of elevation of the top of the tower is observed to be 60^(@). Form a point 40m vertically above the first point of observation,the angle of elevation of the top of the tower is 30^(@). Find the height of the tower and its horizontal distance from the point of observation

If the volume and surface area of a sphere are numerically the same, then its radius is (a) 1 unit (b) 2 units (c) 3 units (d) 4 units

If the angle of elevation of a tower 18^(@) and the distance between top and point of observation is 4, Find the height to tower.

The distance between the points A(2,-3) and B(2,2) is a)2 units b)3 units c)4 units d)5 units

Find the points of the x-axis, whose distances from the line x/3+y/4=1 are 4 unit is.

The distance of the point (4,5,6) from the XZ plane is (a)2 units (b)3 units (c)4 units (d)5 units

The abscissa of point A is equal to its ordinate, and its distance from the point B(1,3) is 10 units, What are the coordinates of A?
