Indefinite amount of solutions.
Answer:
-2
Step-by-step explanation:
First remove parenthesis. Next collect the like terms. Next move terms. Next collect the like terms and calculate. Divide both sides by 8. Your answer is -2
Answer:
![5.77\ \text{m}](https://tex.z-dn.net/?f=5.77%5C%20%5Ctext%7Bm%7D)
![11.54\ \text{m}](https://tex.z-dn.net/?f=11.54%5C%20%5Ctext%7Bm%7D)
Step-by-step explanation:
p = Height of pole
h = Length of role
b = Distance between the bottom of the rope and bottom of the pole = 10 m
= Angle between the rope and the ground = ![30^{\circ}](https://tex.z-dn.net/?f=30%5E%7B%5Ccirc%7D)
![\tan\theta=\dfrac{p}{b}\\\Rightarrow p=b\tan\theta\\\Rightarrow p=10\tan30^{\circ}\\\Rightarrow p=5.77\ \text{m}](https://tex.z-dn.net/?f=%5Ctan%5Ctheta%3D%5Cdfrac%7Bp%7D%7Bb%7D%5C%5C%5CRightarrow%20p%3Db%5Ctan%5Ctheta%5C%5C%5CRightarrow%20p%3D10%5Ctan30%5E%7B%5Ccirc%7D%5C%5C%5CRightarrow%20p%3D5.77%5C%20%5Ctext%7Bm%7D)
The length of the rope is ![5.77\ \text{m}](https://tex.z-dn.net/?f=5.77%5C%20%5Ctext%7Bm%7D)
![\cos\theta=\dfrac{b}{h}\\\Rightarrow h=\dfrac{b}{\cos\theta}\\\Rightarrow h=\dfrac{10}{\cos30^{\circ}}\\\Rightarrow h=11.54\ \text{m}](https://tex.z-dn.net/?f=%5Ccos%5Ctheta%3D%5Cdfrac%7Bb%7D%7Bh%7D%5C%5C%5CRightarrow%20h%3D%5Cdfrac%7Bb%7D%7B%5Ccos%5Ctheta%7D%5C%5C%5CRightarrow%20h%3D%5Cdfrac%7B10%7D%7B%5Ccos30%5E%7B%5Ccirc%7D%7D%5C%5C%5CRightarrow%20h%3D11.54%5C%20%5Ctext%7Bm%7D)
The length of the pole is ![11.54\ \text{m}](https://tex.z-dn.net/?f=11.54%5C%20%5Ctext%7Bm%7D)
