Question

Angle A=190, Angle B=40, Angle C=-96
List the sides of triangle ABC in order from shortest to longest.


*EDIT* Full question:m angle A = 8x –2, m angle B = 2x – 8, and m angleC = 94 – 4x. List the sides of triangle ABC in order from shortest to longest.

Answer 1

so??

Answer 2

i don't see what you want...review your question up there

Answer 3

???????????????

Answer 4

How can an angle be negative? :/

Answer 5

its not posible

Answer 6

Don't listen to anyone in this, they don't know what they're talking about.

Draw out the triangle and I'll help you along.

Answer 7

All of this is completely possible.

Answer 8

what????? dont know what were talkin about??????????? really sir

Answer 9

m angle A = 8x –2, m angle B = 2x – 8, and m angleC = 94 – 4x. List the sides of triangle ABC in order from shortest to longest.

Answer 10

I looked at another article on here that had the first half of this listed, and when i worked out the problems for X, the above angles are what I got.

Answer 11

Okay, now that's better!

You've been given that m angle A = 8x –2, m angle B = 2x – 8, and m angleC = 94 – 4x.

Sum of the 3 angles of a triangle is 180

thus, equate m<A + m<B + m<C to 180

Do that, and first find out the value of x, and hence the 3 angles.

Answer 12

That is what I did, and I got those angles. Could you try to work it out and see if you get something different?

Answer 13

What are the 3 angles that you got?

Answer 14

A=190, B=40, C=-96

Answer 15

Eh? What do you get as x?

Answer 16

24
...

Answer 17

Would you mind showing my your calculations?

Answer 18

me*

Answer 19

wait

Answer 20

I think I just spotted one error

Answer 21

Oh!

Answer 22

180=8x-2+2x-8+94-4x
6x+84=180
180-84=96

6x=96
96/6=16

?

Answer 23

Perfect :D :P

Answer 24

ok let me rework something

Answer 25

8(16)-2 2(16)-8 94-4(16)
126 24 30
Am I correct?

Answer 26

Oh yes, you are :D

Answer 27

Ok, but now I still need to know which sides are longest(I don't have a protractor to draw the triangle)

Answer 28

The side opposite to the largest angle has to be the longest side..

Answer 29

Sorry I meant the length of all sides, Is there a formula I can use?

Answer 30

That's what i mean

here, <A is the largest, no?
this means, the side opposite to <A is the longest ..

Similarly, <B being the smallest angle,
makes the side opposite to it the shortest.

Do you get it?

Answer 31

Ok thanks so, BC is largest, AC is smallest?

Answer 32

Yep!

Answer 33

Thanks! Problem solved!

Answer 34

:D
