Answer:
7949.13 feet
Step-by-step explanation:
We are given that,
Angle of depression from the spot to the group = 39°
Height of Grand Canyon = 5000 feet.
So, we will get the following figure of a right triangle.
<em>As, 'in a right triangle, the angles and the sides can be written in trigonometric form'.</em>
We get, ![\sin A=\frac{perpendicular}{hypotenuse}](https://tex.z-dn.net/?f=%5Csin%20A%3D%5Cfrac%7Bperpendicular%7D%7Bhypotenuse%7D)
i.e. ![\sin 39=\frac{5000}{x}](https://tex.z-dn.net/?f=%5Csin%2039%3D%5Cfrac%7B5000%7D%7Bx%7D)
i.e. ![x=\frac{5000}{\sin 39}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B5000%7D%7B%5Csin%2039%7D)
i.e. ![x=\frac{5000}{0.629}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B5000%7D%7B0.629%7D)
i.e. x = 7949.13 feet
Thus, the line of sight distance is 7949.13 feet.
The first answer I have to just guess.
Step-by-step explanation:
Answer:
3.4
Step-by-step explanation:
Let the original price of the bag be = P, the selling price =2.89 after a 15% discount,
Then, Selling price= Original price- Discount on original price
![2.89=P-P(0.15)](https://tex.z-dn.net/?f=2.89%3DP-P%280.15%29)
![2.89=P(1-0.15)](https://tex.z-dn.net/?f=2.89%3DP%281-0.15%29)
![2.89=0.85P](https://tex.z-dn.net/?f=2.89%3D0.85P)
![P=\frac{2.89}{0.85}](https://tex.z-dn.net/?f=P%3D%5Cfrac%7B2.89%7D%7B0.85%7D)
![P=3.4](https://tex.z-dn.net/?f=P%3D3.4)
Thus, the original price was 3.4.
