What height on the wall will a 15 foot ladder reach if it is placed 3.5 feet from the base of the wall...???
2 answers:
Answer:
14.6 feet
Step-by-step explanation:
Let the height of the ladder be the hypotenuse, the distance from the wall be the base and the height till the ladder reaches be the perpendicular.
Using Pythogoras theorem,
H^2 = p^2+b^2
p^2 = H^2-b^2
p = under root(H^2-b^2)
p = under root(225 - 12.25)
p = 14.6 feet
14.6
hope this helps have a blessed day

Answer:
lol that just means free points for me. ;)
AB=6cm AC=12cm
AC² = AB + BC²
12² = 6² + CB²
CB² = 12² - 6²
CB² = 144 - 36
CB² = 108
CB = √ 108 cm.
sin 55° = CB / CD
0.81915 = √108 / CD
CD = 10.392 / 0.81915
CD = 12.686 cm
