Question 891176
This forms a quadrilateral with angle measures 65, t, t, and x.
x is outside of the circle, 65 is at the circle center, and two angles of t each are opposite from each other.


TANGENT, means the angle made ON the circle is 90 degrees.  t=90 degrees.


65+90+90+x=360, because quadrilateral has 360 degrees for sum of interior angle measures.
x=360-65-180
x=180-65
x=115
