Question

question 8 of 10 which angles are obtuse? check all that apply. a. ∠mlk b. ∠dbc c. ∠gfe d. ∠dba

Explanation:

Step1: Define obtuse angle

An obtuse angle is >90° and <180°.

Step2: Analyze ∠MLK

At L: LM (right) and LK (up). Likely 90° (right angle), not obtuse.

Step3: Analyze ∠DBC

At B: BC (right) and BD (up/angled). If >90°, it's obtuse.

Step4: Analyze ∠GFE

At F: FG (right) and FE (up). Small angle, acute.

Step5: Analyze ∠DBA

At B: BA (left) and BD. Supplementary to ∠DBC; if ∠DBC>90°, this <90°, acute.

Answer:

B. ∠DBC
