Question

STOP SCROLLING :) 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?

A.They are similar because BR:DB is 1:3 and KE:YK is 1:3

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

C.They are not similar because BR:DB is 1:2 and KE:YK is 1:3.

D.They are not similar because BR:DB is 1:3 and KE:YK is 1:2.

Answer 1

This is like deciphering the Navajo WW2 Code...

Answer 2

Well, have you attempted to determine which one is true by determining the area of each triangle?

Answer 3

hahaha. I agree. & no, I honestly don't even know where to start :( so lost

Answer 4

Ok. Well, the give you the side lengths for each triangle. and we know the formula for the area of a triangle is A=bh/2 right?

Answer 5

Or...maybe there's not asking for area, and its simpler than that.

Answer 6

Maybe they just want yo uto compare side lengths. In that case you can use Pythagorean theorem, c^2=a^2+b^2, and solve for the length!

Answer 7

ok?

Answer 8

the ratios are in relation to their length.

Answer 9

Ok . Can you show me how this is done? I have three more problems i have to do like this

Answer 10

oh boi.

Answer 11

Ok, so I'll help you find the length for one of them. From there I expcet you to be able to find any other lengtths neccessary for this question. I will then assist you in finding ratios.

Answer 12

Sgtart with DB

Answer 13

You can see it forms a triangle's side.

Answer 14

The "base" of this triangle is 5 units, and the height is 2 units, if you look at this like a right angle triangle.

Answer 15

a=5, and b=2.

Answer 16

sub those into c^2=a^2+b^2.

Answer 17

c^2=5^2+2^2.

Answer 18

Then you solve for C.
C^2=25+4
C^2=29
c=sqrt(29)

OK?

Answer 19

Ok, what about the ratio's?

Answer 20

ok, so say the length of BR is 24, and DB is 12. Well that's a ratio of 24:12. But, if you can divide out a whole number form each side, then do so.
Here, both 24 and 12 can be divided out by 2, 3, 6, and 12. What do you choose? The biggest number.
So, then the ratio is 2:1.
