3) O is the center of the circle. Assume that lines that appear to be tangent are tangent. What is the value of x?
Accepted Solution
A:
We know that the angles of a quadrilateral add to a 360° angle. And there is two right angles at the point of the tangent. We deduce the equation: x+90+90+132=360 then x=360-90-90-132=48. Answer x=48.
