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°

Answer:
A ) Distributive property, subtraction property of equality, subtraction property of equality, division property of equality.
Step-by-step explanation:
The given equation:
4 ( x + 5 ) = 2 x + 2
4 x + 20 = 2 x + 2 ( Distributive property ),
because: 4 · x + 4 · 5 = 4 x + 20
Then follows : 4 x - 2 x + 20 = 2 x - 2 x + 2 ( Subtraction property of equality )
2 x + 20 = 2
After that:
2 x + 20 - 20 = 2 - 20 ( Subtraction property of equality )
2 x = - 18
Finally:
x = - 18 : 2 ( Division property of equality )
x = - 9
Easy you take 4.75 and multiply it by 5 and you get $23.75
