Given:
BOAT is an isosceles trapezoid.

If BO = 12 and TA = 6, find the length of the median.

7?
8?
9?

Answer 1

the median is the average of them

Answer 2

or just add the halfs ..

Answer 3

What do you mean?

Answer 4

i mean, find the average of the lengths given ...

Answer 5

since the formula is just: (a+b)/2, that amounts to adding the halfs: a/2 + b/2

Answer 6

And the question, If T = 130°, find O.
Would this answer be O= 130?

Answer 7

So the answer would be 8?

Answer 8

Erm no that wouldnt be 8. I am still alittle confused where you get the halfs at.

Answer 9

spose you had 2 unequal strings:

8: --------
14: --------------

to make them equal, you would have to find the difference between them:

14 - 8 = 6

take half of the difference from the longer piece: 14 - 3 = 11
and add it to the shorter piece: 8 + 3 = 11
now they are both 11 long

we could have gotten the same results if we had added
the strings together: 14 + 8 = 22

and cut them in half: 22/2 = 11

so to find the median (the middle) of 12 and 6; we can
simply add them together: 12+6 = 18

and divide them in half: 18/2 = 9

Answer 10

im not sure how to approach the t=130, doesnt seem to be enough information to me
