Answer:
SAS postulate
Step-by-step explanation:
AD (common)
AC = BD (both are diameters)
Angle COD = Ange AOD (vertically opposite angles)
Angle CAD = Angle BAD (angle on the circumference is half the angle at the centre)
Therefore, ABD and DCA are congruent by SAS postulate
Composite figure is made up of 4 triangles and a square.
Area of Square = Length x Length
Area of Square = 12 x 12
Area of Square= 144 cm²
Area of triangle = 1/2 x base x height
Area of triangle = 1/2 x 12 x 8
Area of triangle = 48 cm²
Area of 4 Triangles = 48 x 4
Area of 4 Triangles = 192 cm²
Total Area = 144 + 192 = 336 cm²
Answer:
graph them and then see if they intersect(but if you notice that the coordss of the second line are all smaller than the coords of the first line, meaning that they wont be touching at all)

Answer:
The length of the rectangle is 159923.5 and the width of 53289.5
Step-by-step explanation:
We will make 2 equations one that is the perimeter and another that is the length with respect to the width
b = w*3+55
2b + 2 w = 426426
we will replace b with (w * 3 + 55) in the second equation
2b + 2 w = 426426
2(w*3+55) + 2w = 426426
we clear w to find its value
6w + 110 + 2w = 426426
8w = 426426 - 110
8w = 426316
w = 426316/8
w = 53289.5
Now that we have the value of w we replace it in the first equation and solve to find b
b = w*3 + 55
b = 53289.5*3 + 55
b = 159868.5 + 55
b = 159923.5
