Answer:
k=21
Step-by-step explanation:
Find the slope of MN which is 1/5 (use the slope formula)
Use the slope formula for AB using k as y_2
Substitute and you get k=21
21-2.25/-2.25-1.5=-5
The lines are perpendicular because the slopes are the negative reciprocal of one another.
Remember that straight lines are 180°. For #1 angle 1 would be 40°, since 140°+40°=180°
138 because 92/4 equals 23 which is the miles per gallon, then you multiply that by 6<span />
