Answer:
59°
Explanation:
Well, as you can see from the figure, the line WU is a diameter which means that it is a straight line. So, Angle WSU is 180° (Because straight angles are 180°)
Also, angle WSU is formed by addition of angle VSW and VSU. The value of VSU is given in the picture. So,
∠VSW + ∠VSU = 180°
∠VSW = 180° - ∠VSU
∠VSW = 180° - 121 (Because ∠VSU is given 121°)
∠VSW = 59°
Therefore, angle VSW is 59 degrees.
So, here you go. I hope you understand my explanation. Have a good day.
