If a triangle equals 180, than what you want to do is add all of the numbers together. 33+21+28= 82.
After that what you want to do is subtract that by the total of the triangle "180"
180-82=98.
I believe 98 is the answer

Answer:
In algebra, like terms are terms that have the same variables and powers. The coefficients do not need to match. Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers.
1 steak costs $9.99
2 steaks cost 2*9.99 = $19.98
This is before tax is applied
Apply the 6% tax to get
6% of 19.98 = (6/100)*19.98 = 0.06*19.98 = 1.1988
which rounds to 1.20 (rounded to the nearest penny)
The sales tax is therefore $1.20
Add this to the previous total (19.98) and we get a grand total of 19.98+1.20 = 21.18 which is the final cost (with tax included)
note: we can multiply 19.98 by the value 1.06 to get 19.98*1.06 = 21.1788 and that rounds to 21.18; so it's a different route to the second answer
