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: 1044cm
Step by Step Explanation :
- separate the shape into a rectangle and a square. Subtract 46 from 21
- the rectangular shape is 30cm by 25cm LxW its 750cm
- the smaller shape on the side is 21 cm by 14cm LxW its 294.
- Add. 294cm + 750cm = 1044cm
Answer:
If the numbers were the same, they'd both be 61
So, try 60 and 62.
x + x+2 = 122
2x = 120
x = 60
Hope that helps!
