Good description (but points should be named with upper-case letters). The triangles being similar means that corresponding angles are congruent. This means measure of angle K equal measure of angle N.

Also, sum of interior angle measures of a triangle is 180 degrees.
measOfAngleK%2B50%2B40=180
Angle K's measure is 90 degrees.
Measure of angle N is also 90 degrees, both because similarity of the triangles as well as sum of measures be 180 degree.
