Question

How many parallelograms can be made if one angle measures 50 degrees and one side is 10 centimeters

Answer 1

So we know that in case of a parallelogram the opposite sides and opposite angles are equal 
so than given that one angle measure 50 degrees so the opposite angle measure 50 degrees too and so in this way the other two opposite angles measures equal 360 -2*50 =360 -100 = 260 degrees so one to one will be 260/2 = 130 degrees 
- in this way bc. given that one side has a length of 10 cm so from this result that the opposite side has 10 cm too 
- and from theses above wrote result that one parallelogram can be made with these given dimensions 

hope thsi will help you
