Answer:
235
Step-by-step explanation:
183.3 ÷ 0.78 = 235
This is due to the rules of division.
785.63-(57+125)
=785.63-182
=603.63
603.63+57.25=$660.87
A trapezoid is isosceles if and only if
(1) The base angles are congruent
(2) The diagonals are congruent
(3) The opposite angles are supplementary
So the description does not guarantee that a trapezoid is isoceles for "Congruent bases".
486.65 is the answer to the question
