The angle formed between the ladder and the house is typically a right angle (90 degrees) if the ladder is resting against the wall of the house. This assumes that the base of the ladder is on the ground and the wall is vertical. If the ladder is leaning at an angle, the specific angle would depend on how far the base of the ladder is from the wall and its height against the wall.
If the angle between the ladder and the ground is 60 deg, and you know the angle between the ground and the wall is 90 deg, then you have a 30-60-90 degree triangle, which is a common triangle. You should memorize this one. The commonest sides of this right triangle are 4-5-6, with the longest side being the hypoteneuse, in this case the ladder leaning from the ground to the wall. The wall is 4m high, the base of the ladder would be 5m out from the wall, and the length of the ladder is 6m.

No, a ladder leaning against a wall is not in equilibrium. Equilibrium would occur if the forces acting on the ladder were balanced, but in reality, the ladder is subject to gravitational force and may slide or topple over if not properly stabilized.
The angle of elevation of the ladder leaning against the wall is approximately 48.59 degrees.

No. if the floor is smooth you must have friction between the ladder and the floor, or the ladder would just slide away. Technically you could do without friction between wall and ladder, but even that can be helpful in preventing the ladder from going sideways.
Can give you one. Leadership is leaning the ladder against the right wall, where management ensures the ladder is properly set up.

The preposition in the sentence is "against." The ladder was leaning against the roof.
