This is the concept of application of geometry; the distance that the ladder should be placed will be given by Pythagorean theorem.
thus;
c^2=a^2+b^2
where, c=hypotenuse, a and b are the legs
hence;
15^2+12^2+b^2
b^2=15^2-12^2
b^2=225-144
b^2=81
getting the square root of both sides;
b=sqrt81
b=9
therefore the ladder should be placed 9 feet from the wall for it to reach 12 feet up the building
Answer:
An equation like 2x + 3 = 7 is a simple type called a linear equation in one ... There are other types of equations, however, that can have several solutions. ... to solve an equation algebraically and you end up with an obvious identity (like 3 = 3)
