Question

Help ...? EF is the midsegment of trapezoid ABCD. Determine the value of x??

Answer 1

A. 8.2
B. 3.8
C. 5
D. 10.7

Answer 2

@love14 what do you think the first step is

Answer 3

the midsegment has average length of the other two sides, so 8.8 is the average value of 12.6 and x. can you find x from here?

Answer 4

\(\bf \textit{midsegment of a trapezoid}=\cfrac{1}{2}(base1+base2)\qquad thus
\\ \quad \\
EF=\cfrac{1}{2}(DC+AB)\implies 8.8=\cfrac{1}{2}({\color{brown}{ x}}+12.6)\)

Answer 5

I think its C.

Answer 6

I tried, the options listed for the equation, and none so far give me 8.8? :(

Answer 7

Wait nvm, I got 5 :)

Answer 8

@love14 you are solving the wrong equation. it should be

\[ \frac{12.6 + x}{2} = 8.8 \]

Answer 9

12.6 + X which is 5. Divided by 2 = 8.8. Did you try it like that?
