As the three longitudinal lines are parallel:
angle 4 = 5 = 6 = 82 degree (corresponding angles) = 9 = 8 = 7 = 82 degrees (vertical angles)
and
angle 11 = 180-82= 98 degrees (linear pair)
so:
angle 10 = 11 = 12 = 98 degrees (corresponding angles) = 3 = 2 = 1 = 98 degrees (vertical angles)
.
hope you got it
Answer:
18
Step-by-step explanation:
To find this we must divide 45 by 20 which gives the answer of 2.25. As we know this we now must multiply that by 8 resulting in to 18.
Therefore the answer is 18
Using addition
x-y+1/2x+y=1+5
x+1/2x+0y=6
3/2x=6

3x=12
x=4
Using the value of x
x-y=1
4-y=1
y=3
With x as 4 and y as 3, their product is 12
And can be written as (4,3)
<span>y=-3x-4
slope = 3
perpendicular to line then slope = 1/3
answer
</span>slope of a line perpendicular to <span>y=-3x-4
