Question

Which angles are obtuse?

Answer 1

Answer:

B. ∠DBC

Step-by-step explanation:

∠DBA is an acute angle

∠GFE is also an acute angle

∠MLK is a right angle, neither acute or obtuse (it's in its own category)

Answer 2

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. Right angles and acute angles are always less than obtuse.

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.

Hence, ∠DBC is the correct answer
