Using symbol "^" for powers. Use Pythagoras - a^2 + b^2 = c^2. This is valid for a triangle with a right angle, which should be more or less accurate for the case mentioned. The longest side, "c", is 20 in this case; the 16 (16 feet above the ground) can be either a or b. Solve for the remaining variable.

The question should be: Is a period placed inside or outside of close quotes at the end of a sentence? It depends on the style guide you're using, and whether your publication is to be official in the 'American English' or 'British English'. In American English, you'll place the period inside the close quotes. In British English, you'll place the period outside the close quotes.

Using Pythagoras' theorem the the foot of the ladder should be 12 feet away from the base of the building.
It is not a proportion. There needs to be aroubd a 75 degree angle from the ground to the base. If it is too flat the ladder can slip out from underneath you. If it is too steep you can tip back. There is usually an angle at the bottom of the ladder if that is flat on the ground then that should be the safest angle (75 degrees)
It should be placed 2 ft from the wall
1/4 the height of the ladder. (flat top on rungs should be level when ladder is placed right.

A ladder should be safe if it is properly constructed and maintained. Both single and extension ladders should be equipped with nonskid safety feet and should be placed on a firm, level surface.

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.
he should bud the ladder so it wouldn't be able to reach
They should be placed with the large cases on the bottom and smaller ones on top
