How many parreleljeje

The correct answer is;

Using this information, each student can prepare an infinite number of parallelograms

Step-by-step explanation:

The given parameters of the parallelogram Emily asks the students to bring are;

The measure of one of the angles of the parallelogram = 50°

The length of of one side of the parallelogram = 10 cm

The shapes which the parallelogram must not be are; rhombus, rectangle, or square

Using the given information, therefore, the number of different parallelograms the students can prepare is given as follows;

The number of different lengths of the other side of the parallelogram = Infinity - 1 = Infinity

Therefore, the number of different parallelograms the students can prepare  is an infinite number of parallelograms
