Answer:
the first one
EBG = 45 (acute)
EBC = 100 (obtuse)
Explanation:
If measured correctly, you'll get 45 degrees on EBG as it's points are 80 and 125. 45 is less than 90 so it's acute. EBC if measured correctly is 100 as it's point are 80 and 180 (easy math here). 100 is more than 90 so it's obtuse, taking out all other options. Therefore the answer is the first one.
