What they want is the measure of angle 3 + the measure of angle 4.
Since angle 3 and angle 4 together create a straight line, this means they are supplementary, or adding up to 180°. So, m<4 + m<3 = 180
Answer:
-6n - 13
Step-by-step explanation:
(-4n - 8) - (2n + 5)
Subtract -4n and 2n.
Then Add 8 and 5.
-6n - 13

Draw a line (1)
(2) Draw a line perpendicular (at an angle of 90 degrees to a given line,plane or surface to this line.)
(3)Then draw a third line.
perpendicular to line 2.
Now line 3 is parallel to line 1. :)
