how many degrees to go all the way around a circle?
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" ?
the "numbers" they give you have x's in them write down all three "expressions" with a plus sign in between them
What? i dont follow
So \[ (8x+10) + (6x) + (10x+10)\]
yes and that must equal 360 \[ (8x+10) + (6x) + (10x+10) = 360 \] because they represent the whole circle.
although the first term should be 8x-10 (not 8x+10)
So @phi is 15 ????
P.S i just plugged it in :)
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
So now part B ?
the angles of the triangle are 1/2 the opposite "arcs" figure out what each arc is (plug 15 into each one )
For B i was gonna but isosceles
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
Well yes i summed it up to 2 out of 3
Am i correct?
what numbers did you get for 8x-10 6x 10x+10 ?
I got 110, 90,160 and oops i meant scalene
and the actual angles of the triangle are 55, 45 and 80 yes, definitely scalene
;) Thanks so much can we do just 2 more :)
