Question Analysis

This question is about identifying an obtuse angle among the given angles in a diagram.

 

Key Concept Explanation

An obtuse angle is an angle that measures greater than 90° but less than 180°.

 

Step - by - Step Solution

Analyze each angle in the diagram:

For ∠RKQ, it is given as 41°, which is less than 90°.

For ∠RKB, ∠RKB = 90°.

For ∠CKB, it is given as 30°, which is less than 90°.

For ∠CKP, it is given as 150°, which is greater than 90° and less than 180°.
