Question

The sum of 3 interior angles of a quadrilateral is 262°. Find the measure of the fourth interior angle.

98
162
82
102

Answer 1

The four interior angles of a quadrilateral always add to 360°, so the answer is 98

Answer 2

The sum of the four interior angles of a quadrilateral always equals
`360^(\circ)`.

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 =
`360^(\circ)-262^(\circ)=98^(\circ)`

Thus, out of the given options, The first option is the correct one.
