Assuming that lines that appear to be tangent are tangent, what is the value of x?
(1 point)
Since the measure of angle O is 128° and we know that the angle formed by a tangent and a radius is always 90°, we can calculate the value of x by using the equation:
angle O + angle x = 180° (sum of angles in a straight line)
128° + 90° = 180°
x = 180° - 128°
x = 52°
Therefore, the value of x is 52°.
