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:
Step-by-step explanation:
2x + 23 + 9x - 5 = 95
11x + 18 = 95
11x = 77
x = 7
2(7) + 23 = 14 + 23 = 37 = m<ABD
9(7) - 5 = 63 -5 = 58 = m<DBC
Step-by-step explanation:
mean=sum of observarion/totalno. 9f ovservation
14+16+x/3=12
30+x=36
x=6
