this is one that i got wrong, can someone explain how to do it the right way?
OpenStudy (anonymous):
D. is 62 degrees.. it got cut off.
ganeshie8 (ganeshie8):
did u solve x already,
if so, wat did u get for x ?
OpenStudy (anonymous):
i got 62 as my answer. not sure about the steps. i did this a while ago.

i think i tried adding both equations together to try to find x.
ganeshie8 (ganeshie8):
okay,
first we must solve x
ganeshie8 (ganeshie8):
since the altitude is also a perpindicular bisector, it is also an angle bisector.
so left angle equals right angle
5x+3 = 2x+18
solving give u, x = 5
ganeshie8 (ganeshie8):
as usual, we're not after x
we're after \(m \angle AZY\)
OpenStudy (anonymous):
15+3=10+18
18=28

ohh, ok
ganeshie8 (ganeshie8):
\(m \angle AZY = 2 \times (5x+3)\)
ganeshie8 (ganeshie8):
plugin x value and simplify
OpenStudy (anonymous):
56
OpenStudy (anonymous):
2*25+3=53

OpenStudy (anonymous):
28+28=56
ganeshie8 (ganeshie8):
careful, paranthesis
OpenStudy (anonymous):
yep :I
OpenStudy (anonymous):
i messed up
ganeshie8 (ganeshie8):
good :) 56 is correct
but do u understand why we took \(2 \times (5x+3)\) ?
think about it when u have time

5(5)= 25. (25+3)=28. 2x28=56! :)
ganeshie8 (ganeshie8):
thats right ! i was trying to ask a different question actually... but ok :)
OpenStudy (anonymous):
oh :C
OpenStudy (anonymous):
i have time to think about it. x)
OpenStudy (anonymous):
oh wow i read that completly wrong. no i dont know why we did that. i know how we did tho. xD

cool, it gets easy, if u see it urself,
it oly complicates if i try and explain u
OpenStudy (anonymous):
ahh. ok
ganeshie8 (ganeshie8):
il explain quick anyways :-
here is the kwy : left angle equals right angle cuz ZB is also angle bisector

Also see that,
AZY = left angle + right angle
OpenStudy (anonymous):
anndd...you lost me. x)
