noA 4th angle would have to be obtuse, because the acute angles could not sustain a quadrilateral.
A quadrilateral with 3 acute angles and 1 obtuse angle is known as a scalene trapezoid. In this type of quadrilateral, three of the angles are less than 90 degrees (acute angles), while one angle is greater than 90 degrees (obtuse angle). The sides of a scalene trapezoid are of different lengths, and the opposite sides are not parallel. This distinguishes it from other types of quadrilaterals such as rectangles or parallelograms.
A trapezoid contains either:two acute angles and two obtuse angles orone acute angle, one obtuse angle and two right angles.
