leg is always less than hypotenuse

ganeshie8 (ganeshie8):

x-2 < 4

OpenStudy (anonymous):

Oh alright what about this one?|dw:1373988590325:dw|

ganeshie8 (ganeshie8):

hmm sorry diagram is confusing, could you take a screanshot and attach please :)

OpenStudy (anonymous):

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

ganeshie8 (ganeshie8):

:) 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

OpenStudy (anonymous):

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

ganeshie8 (ganeshie8):

np :)

OpenStudy (anonymous):

can you help me with two more?

ganeshie8 (ganeshie8):

shoot

OpenStudy (anonymous):

ganeshie8 (ganeshie8):

do you see little square box

ganeshie8 (ganeshie8):

it means 90

ganeshie8 (ganeshie8):

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

ganeshie8 (ganeshie8):

hey i need to go out run an errand

ganeshie8 (ganeshie8):
