its wrong, it states line ET is tangent to circle A at point T this means that line NT will be perpendicular to line ET, or that angle NTE is a 90 degree angle now interior angles of triangles add up to be 180 egrees, you know TNG is 25, so 90+25+ NET=180 or 180-90-25=NET and 90+25+50 = 165 which is not 180 which is the reason your answer is incorrect
