Answer: You add up all the terms given of EACH angle, and make this an addition problem that is "equal to 180" ; since all triangles have three angles that add up to 180 degrees. Then you solve for "x".
__________________________________________________
(as follows) ; to get: " x = 29 ⅔ ° " .
_______________________________________
3x + 4 + 2x + x + 8 = 180 ;
_______________________________________
Combine the "like terms" ;
3x + 2x + x = 6x ;
4 + 8 = 12
So, we have: 6x + 12 = 180 ;
Now, subtract "12" from each side of the equation:
__________________________________________
6x + 12 − 12 = 180 <span>− 12 ;
</span>__________________________________________
to get:
6x = 178 ;
Now, divide EACH SIDE of the equation by "6" ; to isolate "x" on one side of the equation; and to solve for "x" ;
______________________________________
6x / 6 = 178 / 6 ;
to get: x = 178/6 = 29 ⅔ ° .
______________________________________
x = 29 ⅔ ° .

Answer: option 2 is the cheapest
Step-by-step explanation:
Option 1 :
10% of 4.99 = 0.499
10% off 4.99 =
4.99 - 0.499 = 4.491
10% of 15.99 = 1.599
10% off 15.99 =
15.99 - 1.599 = 14.391
10% of 30.99 = 3.099
10% off 30.99=
30.99 - 3.099 = 27.891
Total = 4.491 + 14.391 + 27.891 = 46.773
Option 2 :
Most expensive item = 30.99
20% of 30.99 = 6.198
20% off 30.99=
30.99 - 6.198 = 24.792
Total = 24.792 + 15.99 + 4.99 = 45.772
Therefore, option 2 is cheaper by 1.001.
Hope this helped :)
