DOES ANYONE KNOW INEQUALITIES IN TRIANGLES??
You'll find out when you post your question! :)
yes
can you construct a triangle that has the sides of 11, 12 , 15 cm
One of the requirements of the construction is that "Sum of the length of any two sides have to be greater than the third side". Do you think the given data satisfy this requirement?
I only have choices yes or no
Based on the requirement, do you think it is a yes or a no?
For example, 3,5,10 cannot be constructed because 3+5 is not greater than 10.
oh ok so the answer to my question is yes?
there is also another version of the question holdf on!
That is correct!
take aline segment=15 cm draw an arc of 11 cm from one end and draw an other arc of 12 cm from the other end cutting the first arc. join the ends . we get the reqd triangle. |dw:1375220539261:dw|
2 sides of the triangle has legths 5 and 16.. describe the possible lengths of the third side 5<x<16 5<x<21 11<x<21 or 16<x<21
@mathmate
The three conditions are: 5+x>16 16+x>5 16+5>x
Since we know that 16>5, so the middle condition is not useful and can be discarded. So can you find the maximum and minimum value of x?
what is > <
> means greater than and < means less than.
If 5+x is greater than 16, what is the smallest possible value for x?
10
10+5=15 is still less than 16. Try again!
im so confused
If x=11, then 5+x=16, so if x is greater than 11, then 5+x would be greater than 16, does that make sense?
kinda
So can you now work on the other inequality? 16+5 is greater than x
I think
So can you interpret the inequality in words?
The left hand side says 15+6 which evaluates to 21. If 21 is greater than x, then x is less than 21, right? so can you now summarize the answer, such that x is greater than a number, and smaller than another?
i tried it on ither problems and i got them all wrong
What did you try?
Exactly what does the question expects as answers?
18m and 23m 5<x<18 5<x<23 5<x<41 18<x<23
Sorry to hear that, either the answers do not correspond to the question (two sides of 5 and 16) or the answers are not correct.
So the question is for 18 and 23 ?
All this time I was working on "2 sides of the triangle has legths 5 and 16.. describe the possible lengths of the third side".
To make life easier, you only have bracket the third side between the sum and difference of the two other sides. So for 5 and 16, you would put 16-5<x<16+5, or 11<x<21 What would you put for 18 and 23?
