A painter leans an 18 foot ladder against the house so that the base of the ladder is 4 feet away from the wall. Approximately how far up the side of the house does the ladder reach?

17.5ft

Step-by-step explanation:

Use Pythagorean theorem

A^2 + B^2 = c^2 where c is the hypotenuse

The ladder leaning against the wall is the hypotenuse.

4^2 + b^2 = 18^2

16 + b^2 = 324

324-16 = b^2

308 = b^2

B = 17.5ft

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
