    Test in the AM, stuck on 2 geometry problems!

    Hi and Help please!!
    I have a test tomorrow first period in geometry and I am stumped on these two problems on the review sheet.

    a) Find QD if QE=11+20 and QD=400 -10 _______________
    a-2 a+3 Q E D
    E is the midpoint




    b) Angle 3 and 4 are supplementary. Find the measure of angle 3

    m>3=78+360 and m>4= 360 + 32
    y y-3
    Thank you to anyone that can help me. I am so tired, I can't see straight!

    is this supposed to be ...

     QE = 11 + \frac{20}{a-2}

     QD = \frac{400}{a+3} - 10

    or something else?


    b) Angle 3 and 4 are supplementary. Find the measure of angle 3

    m>3=78+360 and m>4= 360 + 32
    y y-3
    same question ...

    m\angle{3} = 78 + \frac{360}{y}

    m\angle{4} = \frac{360}{y-3} + 32

    ???

    Panic city, Here are the problems

    QE=11+ 20/(a-2) QD=400/(a+3) -10
    E is midpoint of line QED


    2nd headache question:m>3=78+360/y andm>4=360/y-3 +32
    Angle 3 and angle 4 are supplementary

    Sorry I typed wrong, I am beat. This test is a make it or break it for me in this course. Any help would be so appreciated.
