The sum of the interior angles of a triangle is 180. Add the three measures given and if you get 180 then those can be the interior angles of a triangle.
Take $360.00 and multiply by .944 and that equals $339.84
Answer:
$22.87
Step-by-step explanation:
12.99+5.99+2.20=21.18
22.18x.08=1.6944
1.69+22.18=22.87
The factored expression would look like this : 3(x+8)(x-8)
