The sum of the four interior angles of a quadrilateral always equals [tex] 360^{\circ} [/tex].
Now, it is given that the sum of 3 interior angles of a quadrilateral is 262°. Thus, the measure of the fourth interior angle will be:
Fourth interior angle = [tex] 360^{\circ}-262^{\circ}=98^{\circ} [/tex]
Thus, out of the given options, The first option is the correct one.
