Answer:
∠ PTQ = 70°
Step-by-step explanation:
The angles subtended by the radii and tangents to the circle , sum to 180°
∠ PTQ + 110° = 180° ( subtract 110° from both sides )
∠ PTQ = 70°
I’m pretty sure it’s 4 < r < 4.1

<h3>How to graph the
trigonometry function?</h3>
The trigonometry function is given as:
y = 5 sin(4x)
To plot the graph, we use the following domain:
x > 0
This represents the minimum value of x
Also, we use
x < π/2
This represents the maximum value of x
When the domain are combined, we have:
0 < x < π/2
This means that the domain that gives a complete cycle is 0 < x < π/2
