Question Analysis

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

 

Key Concept Explanation

A right angle is an angle that measures exactly 90°.

 

Step - by - Step Solution

Analyze each angle in the diagram:

For ∠RKB, since ∠RKQ = 41° and ∠QKP = 49°, then ∠RKP=41° + 49° = 90°. And ∠RKB and ∠RKP form a straight - line (180°), so ∠RKB = 90°.

For ∠CKP, it is given as 150°, which is not a right angle.

For ∠CKB, it is given as 30°, which is not a right angle.

For ∠RKQ, it is given as 41°, which is not a right angle.
