Answer:
1 and 3 are both perpendicular to segment NY
Step-by-step explanation:
1. Find the slope of line NY
slope of NY = 5-(-7)/-11-5 = - 3/4
Any line that is perpendicular to NY should have a slope of the inverse of negative slope of NY.
2.Find the slope of perpendicular lines
the inverse of negative slope of NY = - (-4/3) = 4/3
I believe the answer is 0.9 because a significant figure is a similar difference
Answer:
56
Step-by-step explanation:
So first you have to multiply 21 by .1 to figure out ten percent
you then get 2.1
you add 21 and 2.1 together and get 23.1
then since you have 3 people you divide by 3 and get 7.7
therefor 7.7 is your answer
