Given: AC = 40. Fill in the reason that justifies each step. (4x+4)+(5x)=(40)
9x + 4 = 40
9x = 36
x = 4

True, every step that was done is correct.

Step-by-step explanation:

Since that whole line of AC equals 40, and that (4x+4)+(5x) also equals the whole line, you can just do it this way: (4x+4)+(5x)=40  Solve for x and x will equal 4.  I even used an algebra calculator to solve for x and the calculator indeed said that x=4 (the image is shown below on the calculator I used to solve for x).

Hope this helped! :)

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse
