Answer:
90°
Explanation:
Data provided in the question
Angle V = right angle = 90°
YX and WX = tangents,
And YV and WV = radii
So, we can say that
Angle Y = 90°
And,
Angle W = 90°
Now as we know that sum of four interior angles is 360°
So,
the equation is
V + Y + W + X = 360°
90° + 90° + 90° + X = 360°
270° + X = 360
Therefore,
X = 360° - 270°
= 90°
