leg is always less than hypotenuse
ganeshie8 (ganeshie8):
x-2 < 4
OpenStudy (anonymous):
Oh alright what about this one?|dw:1373988590325:dw|
ganeshie8 (ganeshie8):

KK :) hold on
OpenStudy (anonymous):
ganeshie8 (ganeshie8):
same, hypotenuse is the boss ! its always the longest side
ganeshie8 (ganeshie8):
so,
x + 4 > 9
OpenStudy (anonymous):
I don't get how you get that? Lol

:) look at the diagram, whats the longest side ?
OpenStudy (anonymous):
x+4 side?
ganeshie8 (ganeshie8):
Yes, BC, being the hypotenuse, its the longest side.
ganeshie8 (ganeshie8):
so it will be greater than any other side
ganeshie8 (ganeshie8):
since the other side is shown as 9
we simply put :-
x+4 > 9

Yeah but would it be x+4 >9 ; x>5 or x+4>9; x < 13 ? o.O
ganeshie8 (ganeshie8):
x+4 > 9
subtract 4
x > 5
ganeshie8 (ganeshie8):
so, it wud be :-
x+4 > 9 ; x > 5
OpenStudy (anonymous):
OHHHHH! okay :) lol thank you

since 90 and 12y are making a straight line,
90 + 12y = 180
solve y
ganeshie8 (ganeshie8):
can you ? :)
OpenStudy (anonymous):
y = 7.5 :)
ganeshie8 (ganeshie8):
Yes !
ganeshie8 (ganeshie8):
we have to find x still

ganeshie8 (ganeshie8):
use this :-
same side interior angles add to 180
90 + 5x+4y = 180
5x + 4y = 90
5x + 4(7.5) = 90
solve x
OpenStudy (anonymous):
x = 12 :p
OpenStudy (anonymous):
so it would be the first one!!!! :) right? lol
ganeshie8 (ganeshie8):
Yes ! good work :)
OpenStudy (anonymous):
thank you :) again
