I know the answer is D

Its something with 45 30 90 or something that one angle on the left

\[\frac12\times base \times \text{(s um of p arallel sides)}\]

you use the 1/2h (b1+b2)

Yes.

But we have to find the value of the line adjacent with 45*/

Yeah how its something with 45 30 90 or something my teacher said i forgot

Use tan ratio to find it.

\[\tan \theta = \frac{opp}{adj}\]
\[\tan 45 = \frac{7}{adj}\]
\[adj = 7\]|dw:1330659614940:dw|

Now you have all the values,
\[\frac12 * 7 * (8+8+3+7)\]Solve.:)

ohh its 7
why do you use tan?

oh alright thanks, got a big test tomorrow!
