1. Problem Description

We are given a circle with inscribed angle L=62\angle L = 62^\circ. We are asked to find the measure of the inscribed angle N\angle N. We know that KN\overline{KN} is a diameter of the circle.

2. Solution Steps

Since KN\overline{KN} is a diameter, the inscribed angle L\angle L subtends a semicircle.
Since the sum of angles in a triangle is 180180^\circ, we can say that the angle LKN=90\angle LKN = 90^\circ because it subtends the semicircle.
Also, since KN\overline{KN} is the diameter, we have LKN=90\angle LKN = 90^\circ.
The sum of the angles in KLN\triangle KLN is 180180^\circ. Therefore,
L+N+K=180\angle L + \angle N + \angle K = 180^\circ.
62+N+90=18062^\circ + \angle N + 90^\circ = 180^\circ.
N=1806290\angle N = 180^\circ - 62^\circ - 90^\circ.
N=180152\angle N = 180^\circ - 152^\circ.
N=28\angle N = 28^\circ.

3. Final Answer

The measure of angle NN is 2828^\circ.
