Answer:
Step-by-step explanation:
Let the length of rope is x and y be the distance of the balloon from the ground,
Given,
The spool of rope that is 125 feet away from the balloon,
By making the diagram of this scenario,
Using Pythagoras theorem,
Differentiating with respect to time (t),
We have,
If time = 20 seconds,
So, x = 15 × 20 = 300 ft ( ∵ distance = speed × time )
By substituting the values,
Since, and x = 300 ft,
Hence, the hot air balloon is rising with the speed of 16.5 ft per sec.

Step-by-step explanation:
square root is a number multiplied by itself for example the square root of 4 is 2 because 2*2=4
Answer:
The value of x is 17°.
Step-by-step explanation:
The two exterior angles on the same side of the transversal are always supplementary.
Therefore, if the measure of two exterior angles on the same side of the transversal are 3x and 7x+10, then we can write
3x + (7x + 10) = 180°
⇒ 10x = 180° - 10° = 170°
⇒ x = 17°
Therefore, the value of x is 17°. (Answer)
Product rule- the first rule for simplifying square roots, which allows us to separate the square root of a product of two numbers into the product of two separate rational expressions
