Answer:
RQ = RS = 3
Step-by-step explanation:
Since RQ and RS are radii of the circle then they are congruent
let RQ and RS be x , then
Using Pythagoras' identity in right triangle QRS
x² + x² = (3
)²
2x² = 18 ( divide both sides by 2 )
x² = 9 ( take the square root of both sides )
x = 
= 3
Thus RQ = RS = 3

Based on the time taken by the jet when flying with the wind versus against it, the rate of the jet and jet streams are:
- In still air = 1,170 mph
- Rate of wind = 170 mph
<h3>What is the speed of the jet?</h3>
The speed of the jet flying against the wind is:
= 3,000 / 3
= 1,000 mph
The speed with the jet stream is:
= 5,360 / 4
= 1,340 mph
Assuming the speed of the jet is x and the rate of wind is y, the formulas are:
x - y = 1,000
x + y = 1,340
Solving gives:
2x = 2,340
x = 1,170 mph
The rate of jet stream is:
x - y = 1,000
1,170 - y = 1,000
y = 170 mph
