Can a parallelogram have two 45 degree angles and two 75 degree angles? Why or why not?

No, the sum of the parallelogram's four angles must be equal to 360

Step-by-step explanation:

All four of a parallelogram's angles must add up to 360. Here, the angles only add up to 45 * 2 + 75 * 2 = 240 degrees.

Also, two adjacent angles must add up to 180. Here, the two adjacent angles 45 and 75 only add up to 120 degrees.

no

Step-by-step explanation:

A parallelogram has to have 4 angles that add to 360 degrees

45+45 + 75+75

90+150

240

This does not equal 360

No

4x and 6y

im not sure though
