Isocoleese means 2 angles are same, normally the base angles
so since it says they measure 42
rememeber that all angles in traingle add to 180
so base angles+vertex angle=180
base angles aer both 42 so
2 times 42+vertex angle=180
42 times 2=84
so
if veretx angle=z then
84+z=180
answer is B
Here is how to solve it with long division and synthetic division.
9x+12=5x+4
9x-5x=12-4
4x=8
x=8/4
x=2
Answer:
Copy all that then paste it to Google and there is a site that I found the answer on but I can't copy it it's to long.
( 9 ÷ 3 ) x 2 = 3 x 2 = 6 marbles ;
