I left the number large enough in case you need to round it off to some other decimal place.
Answer:
24 degrees
Step-by-step explanation:
when you have an angle that goes to the end of a circle you divide it by two, if the end of the triangle went to O it would be 48 degrees
The answer is B by inspection, there really isn't any work to show. You could check every wrong answer to prove it's wrong but that's not needed.
Using the circle theorems, we have proven that m ∠RTW = 15°
<h3>Circle theorems </h3>
From the question, we are to prove that m ∠RTW = 15°
In the given diagram,
measure of arc ST = 30°
∴ m ∠SRT = 30°
m ∠SRT = ∠T + ∠W ( <em>Exterior angle of a triangle equals the sum of the two remote angles</em>)
Also,
∠T = ∠W (<em>Radii of the same circle</em>)
∴ m ∠SRT = ∠T + ∠T
m ∠SRT = 2 × ∠T
30° = 2 × ∠T
∠T = 30° /2
∠T = 15°
∴ m ∠RTW = 15°
Hence, we have proven that m ∠RTW = 15°

Count the number of grids for each side length.
UV = 5 units
VW = 6 units
Now, for UW use the pythagoras theorem to calculate.
Therefore, the perimeter is 5 + 6 + 7.8 = 18.8 units.
