Coordinates : A(1,2) B(-5,6) C(7,-4) D(-2,t) - All are taken in order
gradient of AB = (6-2)/(-5-1) = 4/-6 = -⅔
since it is quadrilateral, AB//CD
gradient of CD = -⅔
equation of CD : y-(-4)=-⅔(x-7)
y+4=-⅔x+14/3
y=-⅔x+⅔
now, sub x=-2 from D(-2,t)
since t is the y-coordinate of point D
t=-⅔(-2)+⅔
t=2
Therefore, t=2
Answer: 18

$540
Step-by-step explanation:
$150 × 4 = $600
$600 ÷ 10 = $60
$600 - $60 = $540
Hi there!
In order to find the value of N, we'll need to set the value of the angle containing the variable n equal to 90. This is because in perpendicular lines, all angles are equal to 90.
WORK:
5n - 25 = 90
5n = 115
n = 23
Answer:
Step-by-step explanation:
36 : 3 = 12
12 : 3 = 4
