Answer:
B. ∠DBC
Step-by-step explanation:
Obtuse angles are angles larger than 90 degrees.
We can easily tell that ∠GFC and ∠MLK aren't obtuse, since ∠GFC is acute and ∠MLK is a right angle. <u><em>Right angles and acute angles are always less than obtuse.</em></u>
<u><em /></u>
Now, for a trickier one. Let's look at ∠DBA and ∠DBC
It's easer to find out what type of angles they are by separating them. (look at image)
See? ∠DBA is acute. And we can easily tell that ∠DBC is an obtuse angle.
