Question

The measure of two sides of a triangle are 3.1 feet and 4.6 feet. What is the LEAST possible measure to the nearest tenth for the third side?
a- 1.6
b- 4.6
c- 7.5
d- 8

Answer 1

3.1 + 4.6 > x
3.1 + x > 4.6
4.6 + x > 3.1

Answer 2

There's a much easier way to do it, but I have temporarily forgotten

Answer 3

Oh, I think I remember

Answer 4

none of those come to an answer that is available . :/

Answer 5

|3.1 + 4.6|<x<|4.6-3.1|

What I posted above does come out to an answer that is available. you just have to work it out

Answer 6

7.7<x<1.5

Answer 7

think of it this way, if you wantt he smallest possible third side, then the first side and second side will be on top of each other. what's the smallest piece that can close the remaining distance?

Answer 8

so maybe 1.6 is the answer

Answer 9

imagine a triangle that's almost completely flat, like this:

Answer 10

how long does the top-left leg have to be to get the remaining distance?
