What is the length of the shadow cast by a 63 foot high pole if a 27 foot high pole casts an 18 foot shadow?
If a 27 ft tall pole casts an 18 foot shadow, a 63 ft tall pole casts an x foot shadow.Put 27/18 and 63/x.Cross multiply, get 27x=1134Divide by 27 on both sides, a 63 foot tall pole casts a 42 foot long shadow.

If A painter leans a 34ft ladder against a building The base of the ladder is 16ft from the building To the nearest foot how high on the building does the ladder reach?
30 feet. And you don't have to round it to the nearest foot. It's exactly 30 feet.

What is the formula for a 15 foot ladder is leaning against a 30foot wall the bottom end of the ladder is 9 feet from the wall how many feet above the ground does the ladder touch the wall?
If you take the trouble to draw a sketch of the situation that you've described, the method of solution, as well as the answer, will jump out at you. The ground, the wall, and the ladder, form a right triangle. The base is 9-ft, and the hypotenuse is 15-ft. If you've been assigned this problem as homework, then you've sat through enough geometry in class to know how to work with the right triangle. The length of the missing side is 12-ft, and it makes no difference how high the wall is, as long as it's high enough to support the upper end of the ladder.
