Complete the coordinate proof of the theorem. Given: ABCD is a rectangle.
Prove: The diagonals of ABCD are congruent.
The coordinates of rectangle ABCD are A(0, 0), B(a, 0), C(__,__ ), and D(0, b).

The length of AC¯¯¯¯¯ is equal to __
.

The length of BD¯¯¯¯¯ is equal to __
.

The diagonals of the rectangle have the same length.

Therefore, AC¯¯¯¯¯ is congruent to BD¯¯¯¯¯.

$320 to $405

step by step explanation:

in one day he earns between $64 and $81

therefore if he works for 5 days, he will earn between 64 x 5 to 81 x 5

= $320 to $405
