Answer 1

Bradley and Kelly are out flying kites at a park one afternoon. A model of Bradley and Kelly’s kites are shown below on the coordinate plane as kites BRAD and KELY respectively.

Which statement is correct about the two kites?
They are similar because BR:DB is 1:2 and KE:YK 1:2.

They are not similar because BR:DB is 2:1 and KE:YK is 1:2.

They are similar because BR:DB is 2:1 and KE:YK is 2:1.

They are not similar because BR:DB is 1:2 and KE:YK is 2:1.

I've already figured out that
\[BR = \sqrt{5}\]
\[BD=\sqrt{20}\]
\[KE=\sqrt{20}\]
\[YK=\sqrt{80}\]
But I'm not sure how to answer the question :c

Answer 2

Try simplifying all the radical expressions to have the same radicand.
