The slopes of perpendicular lines are negative reciprocals
The negative reciprocals of -2/3
is 3/2
The measure of angle 4 would be the same as its opposite exterior angle which is given. It will have a measurement of 38 degrees. These angles are called alternate exterior angles. Hope this answers the question. Have a nice day. Feel free to ask more questions.
The slope of line D is also -4 because the lines are perpendicular.
