Answer 1

This is the Hinge theorem if I am understanding the question, as it is not asked. I am assuming that it wants to know which is correct as in Multiple Choice?

DE is across from the smaller angle (63 degrees) and CF is across from the larger angle (98 degrees) therefore CF will be greater than DE.

Think about it. If you open a door 63 degrees and you open a door 98 degrees - which is opened wider? The 98 degree door.

I hope this helps.
