Question

The mesures of the interior angles of a triangle are represented by 2x+10 and 3x+40. Which of the following is the mesure of the smallest angle of this triangle?
1.)50
2.)88
3.)42
4.)16

Answer 1

But there should be 3 sides ?

Answer 2

oh oops my bad its 2x+10, 5x-30 and 3x+40.

Answer 3

Do you know what is the sum of angles ?

Answer 4

no I dont know any of this... I dont get it

Answer 5

Sum of interior angles=(n-2)*180

Where n=3

Now find Sum of interior angles :)

Answer 6

what?

Answer 7

Sum of interior angles=(3-2)*180
=

Answer 8

What will Sum of interior angles be ?

Answer 9

idk

Answer 10

No one know until you do the maths here -_-

Sum of interior angles=(3-2)*180

=1*180


2x+10+ 5x-30 + 3x+40 =180

Now solve for x.

Answer 11

okay so then whats x?

Answer 12

Do it your self,no one is gonna tell.

Answer 13

is it 50?

Answer 14

No

Answer 15

20?

Answer 16

Stop fooling around and solve it

Answer 17

x=20 right?

Answer 18

I am not telling.

Answer 19

Solve it and show me the working.

Answer 20

you add all the xs then divide

Answer 21

Yes add them and show me what you got.

Answer 22

i got 16

Answer 23

is that right?

Answer 24

Yes :)

Answer 25

thanks(:

Answer 26

16 is not the answer

Answer 27

oh then how do i get the answer?

Answer 28

16 is the value of x, you still need to plug it into your angle equations.

Answer 29

Plug 16 into the x of: 2x+10, 5x-30 and 3x+40.

See which is smallest.

Answer 30

so it would be 2(16+20) and would you multiply?

Answer 31

\[
2(16)+10 = ? \\
5(16)-30 = ? \\
3(16)+40 = ?

\]

Answer 32

Also you should give hba a medal.

Answer 33

42
50
88

Answer 34

so it would be 42?

Answer 35

Yeah.

Answer 36

thanks
