ganeshie8 (ganeshie8):
hint : SIDE opposite to smallest ANGLE is the shortest
OpenStudy (annipuppi):
So LK is the shortest?
ganeshie8 (ganeshie8):
look at the triangle,
wats the smallest angle ?
OpenStudy (annipuppi):
LJK

Yes ! LK is the shortest side !
ganeshie8 (ganeshie8):
wats the next small angle after LJK ?
OpenStudy (annipuppi):
JKL
ganeshie8 (ganeshie8):
so the side opposite to JKL will be next short side

So the answer is LK, JL, JK?
ganeshie8 (ganeshie8):
Yup ! good job !!

Okay can you help me with this too? What is the range of possible values for x? The diagram is not to scale
ganeshie8 (ganeshie8):
look at the pic,
the side opposite to angle 58 is 11
ganeshie8 (ganeshie8):
but the side opposite to angle 5x+3 is just 8 right ?

ganeshie8 (ganeshie8):
use this :-
angle opposite to shorter side will be smaller
ganeshie8 (ganeshie8):
5x + 3 < 58
solve x
OpenStudy (annipuppi):
x<11
ganeshie8 (ganeshie8):
yes, thats the upper limit.
Also,
the angle cannot be <= 0
so,
5x + 3 > 0
solve x
OpenStudy (annipuppi):
Is it x>-0.6?

ganeshie8 (ganeshie8):
Correct !
-0.6 < x < 11

Okay I just need help with one more. Given triangle DEF with D(-4,-2), (E(-1,8), and F(5,4). Find the median DT in point-slope form.
