Answer:
125
Step-by-step explanation:
5/4=x/100
x=500/4
x=125
Answer:
18/10
Step-by-step explanation:
Answer:
x = 11
Step-by-step explanation:
- Vertically opposite angles are equal
- Angles around a point add up to 360°
Therefore, 
Part A
The first thing we must do in this case is to hide the slopes of each line.
line m:
m = (- 4-3) / (0 - (- 4))
m = -7 / 4
Line n:
n = (- 2-2) / (3-1)
n = -4 / 2
n = -2
Answer:
Lines m and n are not parallel because their slopes are different.
Part B:
We look for the slope of the K line:
k = (1 - (- 3)) / (4 - (- 3))
k = 4/7
We observe that it is true that:
k = -1 / m
Answer:
The lines are perpendicular.
