Using one of the circle theorems, we have proven that the measure of ∠RTW is 15°
<h3></h3><h3>Circle Geometry </h3>From the question, we are to complete the proof
From the given information,
∴ m ∠SRT = 30°
Now, by one of the circle theorems, we have that
Angle at the <u>center</u> is twice the angle at the <u>circumference</u>
∴ ∠RWT = 30°/2
∠RWT = 15°
Consider ΔRTW
/RT/ and /RW/ are radii
Therefore, ΔRTW is an isosceles triangle
Then,
m ∠RWT = m ∠TRW (<em>Base angles of an isosceles triangle</em>)
∴ m ∠RTW = 15°
Hence, the measure of ∠RTW is 15° as proven above
