Answer 4

@amistre64

Answer 5

@pooja195

Answer 6

yes, 360. notice that your circle is divided into 3 pieces and if you add up the 3 pieces you should get 360

can you write down the "sum" ?

Answer 7

120

Answer 8

@phi

Answer 9

:/

Answer 10

the "numbers" they give you have x's in them
write down all three "expressions"
with a plus sign in between them

Answer 11

What? i dont follow

Answer 12

Oh wait

Answer 13

So
\[ (8x+10) + (6x) + (10x+10)\]

Answer 14

?

Answer 15

yes and that must equal 360
\[ (8x+10) + (6x) + (10x+10) = 360 \]
because they represent the whole circle.

Answer 16

although the first term should be 8x-10 (not 8x+10)

Answer 17

Oops sorry

Answer 18

So @phi is 15 ????

Answer 19

is it*

Answer 20

P.S i just plugged it in :)

Answer 21

yes, that is one way to do the problem.
you could also add up the x's
8x+6x+10x= 24x
and -10+10 = 0
so it simplifies to
24x= 360
x= 360/24 = 15

Answer 22

So now part B ?

Answer 23

the angles of the triangle are 1/2 the opposite "arcs"
figure out what each arc is (plug 15 into each one )

Answer 24

huh?

Answer 25

For B i was gonna but isosceles

Answer 26

if you get the same number for each arc you have an equilateral triangle.
if 2 out of the 3 are the same, it's isosceles
if all 3 are different , it's scalene

Answer 27

Well yes i summed it up to 2 out of 3

Answer 28

Am i correct?

Answer 29

what numbers did you get for
8x-10
6x
10x+10 ?

Answer 30

I got 110, 90,160
and oops i meant scalene

Answer 31

and the actual angles of the triangle are 55, 45 and 80
yes, definitely scalene

Answer 32

;) Thanks so much can we do just 2 more :)
