Answer:
x = 120
Explanation:
The segments to the circle from an external point are tangents
The angle between a tangent and a radius at the point of contact = 90°
The sum of the interior angles of a quadrilateral = 360° , then
60 + 90 + 90 + x = 360
240 + x = 360 ( subtract 240 from both sides )
x = 120
