Answer:
5. D 6. B 7. C
Explanation:
All side lengths of a rhombus are the same therefore the length of WZ must be 4cm.
The sum of all the angles in a rhombus add up to 360 degrees, since we already have 2 100 degrees( opposite interior angles are the same) then the rest must be 80 degrees angles.
This might be wrong it has been a long time since I did these type of questions, tell me if this helps.
