Answer:
All rungs are perpendicular to a side of a ladder.
Step-by-step explanation:
The problem tells us that ALL the rungs of a ladder are parallel.
It also tells us that the top rung (which is a subset of all the rungs) is perpendicular to a side of the ladder.
But if this top rung is perpendicular to a side but we know that ALL rungs are parallel, then this top rung is also parallel to the other ones and therefore, all the other rungs are also perpendicular to a side of a ladder.
Answer:
the ratio of resolution will be 
Explanation:
We have given the diameter of Telescope A is 1 meter
And diameter of telescope B is 6 meter
We know that resolution of telescope is inversely proportional to diameter of the telescope
So 
We have to find the ratio of resolution of B to A
So 
So the ratio of resolution will be
