Question

Is my answer right?

Answer 1

what calculation did you do?

Answer 2

I just thought that the other side is parallel to that side? @jtvatsim

Answer 3

when dealing with a kite, you have two sides that are equal to each other and two other sides that are equal to each other like in this picture.

Answer 4

none of them are necessarily parallel

Answer 5

So, the perimeter is : P = 2a + 2b, where a is the length of one pair and b is the length of the other pair

Answer 6

The question wants the length of the opposite side so by using the picture we see that the opposite sides will have different lengths

Answer 7

Plug into the equation for perimeter and we get:

52 = 2(19) + 2b

All we need to do is solve for b and we will know the length of the opposite side.

Answer 8

See if that helps. :)
