Answer:![\theta =68.96^{\circ}](https://tex.z-dn.net/?f=%5Ctheta%20%3D68.96%5E%7B%5Ccirc%7D)
Step-by-step explanation:
Given
length of ladder ![L=15\ ft](https://tex.z-dn.net/?f=L%3D15%5C%20ft)
Height of light from floor ![h=14\ ft](https://tex.z-dn.net/?f=h%3D14%5C%20ft)
so Jamie should inclined the ladder at an angle of \theta with the floor
such that ![\sin \theta =\frac{h}{l}](https://tex.z-dn.net/?f=%5Csin%20%5Ctheta%20%3D%5Cfrac%7Bh%7D%7Bl%7D)
![\Rightarrow \theta =\sin ^{-1}\frac{h}{l}](https://tex.z-dn.net/?f=%5CRightarrow%20%5Ctheta%20%3D%5Csin%20%5E%7B-1%7D%5Cfrac%7Bh%7D%7Bl%7D)
![\Rightarrow \theta =\sin ^{-1}(\frac{14}{15})](https://tex.z-dn.net/?f=%5CRightarrow%20%5Ctheta%20%3D%5Csin%20%5E%7B-1%7D%28%5Cfrac%7B14%7D%7B15%7D%29)
![\Rightarrow \theta =68.96^{\circ}](https://tex.z-dn.net/?f=%5CRightarrow%20%5Ctheta%20%3D68.96%5E%7B%5Ccirc%7D)
Answer:
8%
Step-by-step explanation:
400/5000*100
0.08*100
8%
Divide 171 by 3. 57
Therefore the middle integer is 57
<span>Therefore the highest integer is "2" higher = 59 </span>
<span>The lowest integer is 2 lower to "balance" the higher digit = 55 </span>
<span>Therefore using common sense rather than "let x=....." the answer is 55, 57 and 59.</span>
The "D" in number 1 is really "1D" so when we combine like terms, we get our final answer:
4D+2
If we do the same thing with number 2, we get:
14x+4
