Thread: Test in the AM, stuck on 2 geometry problems!

1. Test in the AM, stuck on 2 geometry problems!

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 ...

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

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

???

3. Panic city, Here are the problems

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