Yes it must have at least one (really, it needs two or more). The sum of the interior angles in a pentagon is 540°.
If you had 4 angles @ 90°, then the fifth angle would need to be 180°, which is a straight line, then it would be a rectangle, not a pentagon, so you need at least two angles, greater than 90°.
some objects that has an obtuse angle is a pentagon, laptop and the objects that is greater than 90 degrees
Because it has five angles it is a irregular pentagon.
It is an obtuse angle. It is an obtuse angle. It is an obtuse angle. It is an obtuse angle.
No, a pentagon cannot have 2 obtuse angles, 2 right angles, and 1 acute angle. The sum of interior angles in a pentagon is always 540 degrees. If a pentagon has 2 obtuse angles (each measuring more than 90 degrees) and 2 right angles (each measuring 90 degrees), the total would already exceed 540 degrees, leaving no room for an acute angle.
A obtuse angle is called an obtuse angle because if obtuse means bigger in degrees and a right angle is 90 degrees than a obtuse angle must be over 90 degrees.

A pentagon.
A regular pentagon has 5 equal sides and 5 equal interior obtuse angles of 108 degrees.

Not sure what the question means. A triangle or quadrilateral may but need not contain an obtuse angle. A pentagon or any polygon with more sides must contain at least one obtuse angle.

Hi A pentagon has 540 degrees and five sides. If it is a regular pentagon, then each angle is 108 degrees. An obtuse angle is greater than 90°. A pentagon can be constructed with 2 obtuse angles and 3 non-obtuse (either acute or right) angles. Example: if it had 3 angles of 90° = 270°. 540° - 270° = 270°, which would be split between 2 angles (each between 90° and 180°).
