X is the answer and one half is part of the answer
Answer:
Usually, when a question says "FG" or "DB" or any of the other letters put together, they mean the line that it connects to. For example: Point A to Point C. However, I can't say so for sure, because This answer most likely has a diagram drawn beside it. If you can put the diagram or picture along with your questions, I can help you out more!
Step-by-step explanation:
Answer:
rotating ΔEAR 180° inside the right angle parallelogram circumscribed by.
original coordinates:
A (-6, 4)
R (-2, 2)
E (-5, -6)
post rotation coordinates:
- A (-2, -6)
- R (-6, -4)
- E (-3, 4)
Since it’s a trapezoid, 111 + b will equal 180, as will 41 + a.
111 + b = 180 means b = 69.
41 + a = 180 means a = 139.
This happens simply because two angles that are positioned that way between parallel lines will always be supplementary. It’s also worth noting that all angles in any quadrilateral will add up to be 360 degrees.
