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:
49*F
Step-by-step explanation:
-39F + 49F = 10F
Answer: 560 tickets
Step-by-step explanation:
3/4 = 420/x; now cross multiply:
3x = 4(420)
3x = 1,680; now divide both sides by 3, and you get x = 560
Answer:
ADC = 60
Step-by-step explanation:
180 - 120 = 60
120 + 120 + 60 + 60 = 360
|x| meaning how much is from x to 0 so for example |4| = 4 and |-10| = 10 ( it could never be a negative) but when the - is on the outside of the two lines then it turns to a negative like for example:
|23|= 23
But then…
-|23|=-23
^because anything that is out of the two lines doesn't mean distance from that number to 0 only the ones inside
