Answer 1

@FibonacciChick666

Answer 2

No it is not 12. Remember only the opposite sides/parallel sides are congruent

Answer 3

So if AD = BC then how do I find it because there is no reference for me to use to find out.

Answer 4

can you find x?

Answer 5

x = 7.5?

Answer 6

yup yup

Answer 7

Yeah but... 7.5 + 4 = 11.5... there is no answer for that.

Answer 8

huh?

Answer 9

AD = X+4

7.5 + 4 = 11.5

Answer 10

...not that i just looked at the q hmmm h/o

Answer 11

hm?

Answer 12

\(x+4=2x-3\)
Definition of a kite.

Answer 13

^follow him

Answer 14

The 12 does not matter. It is the length of the || sides. The | side on the rotated cite is the two equations.

Answer 15

Get it now?

Answer 16

I think so, thanks!

Answer 17

Since you just replied... let me go over a little more.

This was a "trick" question. The real idea of "trick" questions is to get you to think a little deeper or creatively.

In this question there were two tricky parts. First, they made it look like a parallelogram, possibly a square. That makes you think the 12 is involved. However, the information they give only supports a kite. They even tell you it is a kite. However, the second tricky bit is that the kite is rotated. That makes you use the kite formulas wrong!

Once you realize those two things, you can eliminate everything other than the (x+4) and (2x-3), set them equal, and finish things.

This is a great example of why you need to read equations carefully. Write down or underline the key parts. In this one: kite, all the measures, and the congruent angles. Then look at what is being asked and see what you need from what is given. In this case, that step eliminates the 12 as being meaning full. The congruent angles tell you how to set up the kite to see the congruent sides. Those congruent sides are \((x+4)=(2x-3)\). Then it is an algebra problem.

Always be careful in reading the problems is the true lesson. Oh, and I misread them at times myself, so there is not 100% proven method to make sure you do not miss things! But the less mistakes you make in reading the problem means the less mistakes are made in answering them because you are answering the right problem!
