    a+36=180 solve for a = 144 b+113=180 solve for b = 67.

    |dw:1367518988559:dw| since AB//DC angles <B and <C are allied angles. <B+<C=180 113+b=180. since AB//DC angles <A and <D are allied angles. <A+<D=180 a+36=180.

    can you help me with this one ? LM is the midsegment of trapezoid ABCD. If AB = 46 and DC = 125, what is LM?

    "The mid-segment of a trapezoid is the segment that joins the midpoints of the non-parallel sides. Its length m is equal to the average of the lengths of the bases of the trapezoid" so LM=(46+125)/2=85.5
