John bought 65 pounds of potatoes. If potatoes sell for $2.50 for ten pounds, how much did John pay for his potatoes?

(C)BC = 13, DB = 24

Step-by-step explanation:

It is given that Side AC and side BD are perpendicular bisectors of each other, then from the figure, we have

DE=EB=12(Side AC and side BD are perpendicular bisectors of each other)

Now, from ΔBEC, we have

=

=

=

Therefore, BC=

Thus, BC=13

Also, DB=DE+EB

DB=12+12

DB=24

Therefore,  BC = 13, DB = 12
