Answer:
-2
Step-by-step explanation:
slope = (y1-y2)/(x1-x2)
= (3-1)/(0-1)
= 2/-1
= -2
It isn't because, it isn't consistent, and it doesn't follow any of the other answer choices. :)
Answer:
you did not finish what you were saying
(1) it can be both exterior of vertex or base. 180-130=50°
vertex is 50°: base=(180-50)/2=65°
base is 50°: vertex= 180-2*50=80°
vertex 50 base 65; vertex 80, base 50
(2)base=180-130=50°
vertex=180-2*50=80°
base 50 vertex 80
X/y = 2 so x = 2y
z/x = 4 so z = 4x but x = 2y so z = 4(2y) = 8y
now you have
x = 2y, z = 8y
x + y + z 2y + y + 8y 11y 11
------------ = -----------------------= ------------- = ----------- = 5 1/2
x 2y 2y 2
answer
C. 5 1/2
