Since it's isosceles, ∠ABC = (180-30) / 2 = 75
Yeah it is true abd it is correct
Answer:
1
Step-by-step explanation:
Answer:
Neither
Step-by-step explanation:
First find the slope for both lines.
m= slope
Line 1: (y2-y1)/(x2-x1)
2-5/4-6
=-3/-2
m=3/2
Line 2: (y2-y1)/(x2-x1)
8-(-1)/2-(-8)
m=9/10
These lines are neither parallel or perpendicular because they don't have the same slope (parallel lines), and they don't have opposite reciprocal slopes either (perpendicular lines).
