Question

which angle in the shape is obtuse? ∠k ∠m ∠j ∠l

Explanation:

An obtuse angle is greater than \(90^\circ\) and less than \(180^\circ\). In the given trapezoid - like shape, \(\angle J\) and \(\angle M\) appear to be right angles (equal to \(90^\circ\)), \(\angle L\) appears to be an acute angle (less than \(90^\circ\)), while \(\angle K\) is greater than \(90^\circ\) (obtuse).

Answer:

\(\angle K\)
