Given: KLMN is a parallelogram,
KA
− the angle bisector of ∠K
LA
− the angle bisector of ∠L

Prove: m∠KAL = 90°

m∠LKN + m∠KAL =_° by reason (Complementry Angles/Corresponding Angles/Sum of Angles Theorem/Supplementry Angles.)

you can't solve x because it is 2 linear equation and you only have one equation

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
