Answer:
(3) 49
Step-by-step explanation:
The circle diagram is attached below. angle mVS = 146°
and  angle mST =  64°. 
 mWT = 360 -64 - 146 = 150 (angle at a point)
∠ VWS = 73° = mVS / 2
 MVW = 180 - 146 = 34 (angle in a straight line)
MVW = 180 -73 - 34 = 73° (angle in a triangle)
∠TMR = 180 - 64 = 116° (angle on a straight line)
∠VMT = 116 + 34 = 150°
∠ MVT = ∠ MTV (base angles of an isosceles triangle)
150 +2∠ mTV = 180
∠ MTV = 15°
∠RVW = 73 - 15 = 58°
∠RVW + ∠ VWS  + ∠VRW = 180
∠VRW  = 180 - 58 - 73 = 49
