Question

PLEASE HELP!!!

Answer 1

Using one of the circle theorems, we have proven that the measure of ∠RTW is 15°

Circle Geometry

From the question, we are to complete the proof

From the given information,

$m\overset{\huge\frown}{ST} = 30 ^\circ$

∴ m ∠SRT = 30°

Now, by one of the circle theorems, we have that

Angle at the center is twice the angle at the circumference

∴ ∠RWT = 30°/2

∠RWT = 15°

Consider ΔRTW

/RT/ and /RW/ are radii

Therefore, ΔRTW is an isosceles triangle

Then,

m ∠RWT = m ∠TRW (Base angles of an isosceles triangle)

∴ m ∠RTW = 15°

Hence, the measure of ∠RTW is 15° as proven above
