3lines are shown. a line with points m, h, k intersects with a line with points j, h, l at point h. another line extends from point h to point n in between angle k, h, j. angle m h l is (3 x + 20) degrees, angle k h n is (x + 25) degrees, and angle j h n is (x + 20) degrees. what is the measure of anglejhn? 25° 45° 50° 95°
