2x+6 = 20
take 6 from both sides
2x = 14
divide by 2 on both sides
x = 7
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
2x - 10 -12x + 6 = 6
-10x -4 = 6
-10x = 10
-x = 1
x = -1
Answer:
9x+3x=12x
180/12=15
9 x 15= 135
3 x 15= 45
135+45=180
x=15
