It is not A, C, or E.

PrincessAdelaide:

A shape with two opposite angles equal to 105° could be a quadrilateral, a parallelogram, a rhombus or a trapezoid Because A quadrilateral: A quadrilateral is a four-sided polygon. The sum of the interior angles in any quadrilateral must be equal to 360 degrees so If the quadrilateral have two opposite angles equal to 105°, then the sum of the other two interior angles must be equal to 360°-2(105°)= 150° A parallelogram: A Parallelogram is a flat shape with opposite sides parallel and equal in length. Opposite angles are congruent and consecutive angles are supplementary so If the parallelogram have two opposite angles equal to 105°, then the measure of each of the other two congruent interior angles must be equal to 180°-105°=75° A rhombus: A Rhombus is a flat shape with 4 equal straight sides. A rhombus looks like a diamond. All sides have equal length. Opposite sides are parallel. Opposite angles are congruent and consecutive angles are supplementary so If the Rhombus have two opposite angles equal to 105°, then the measure of each of the other two congruent interior angles must be equal to 180°-105°=75° A trapezoid: A trapezoid is a 4-sided flat shape with straight sides that has a pair of opposite sides parallel so If the trapezoid have two opposite angles equal to 105°, then the sum of the other two interior angles must be equal to 360°-2(105°)= 150°
