Answer: <LNR = 57°
Explanation: In the diagram shown, <BNL and <LNR form <BNR which is a right angle, meaning it measures 90 degrees.
Another way to think about it is that we know <BNJ is a right angle, <BNL measures 30 degrees, and <JNR is a straight angle or 180 degrees.
So we can create the equation 90° + 33° + <LNR = 180°.
Solving from here, we find that <LNR = 57°.
