Answer: ![x](https://tex.z-dn.net/?f=x%3C-1)
Step-by-step explanation:
![-5x-15>10+20x](https://tex.z-dn.net/?f=-5x-15%3E10%2B20x)
Subtract 20x
![-5x-20x-15>10](https://tex.z-dn.net/?f=-5x-20x-15%3E10)
add 15
![-5x-20x>10+15](https://tex.z-dn.net/?f=-5x-20x%3E10%2B15)
Combine like terms
![-25x>25\\](https://tex.z-dn.net/?f=-25x%3E25%5C%5C)
Divide by -25 (NOTE: When dividing or multiplying by negative numbers the inequality sign flips.)

Answer:
Once Dawn is going going back to sea level.
Step-by-step explanation:
The height of the balloon above the ground is about 7.07 feet.
<h3>
What is trigonometric ratio</h3>
Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
Let h represent the height of the balloon from the ground, hence:
sin(45) = h/10
h = 7.07 feet
The height of the balloon above the ground is about 7.07 feet.
