Answer:
hi
Step-by-step explanation:
lolol
Area of polygon = 1/2 pa. So it would be 0.5 x 6 x 3. The fire the area is 9
We have to know the angle that is not labelled. (lets call it y)
9x + y= 180
and the sum of the angles of a triangle is 180
5x + (9+x) + y=180
2 simultaneous equations
Option A: 156 + 179 + 25 + 25 = $385
Option B: 334 + 15 + 15 = $364
Option B is cheaper. 10% of $364 is $36.40. That is what you would save with the third option.
Jayla payed $36.90 i got this because i multiplied 3 times 15 and got 45 then i did .18 times 45 which is 8.1 (8.1 is how much will be taken off) and then i subtracted 45-8.1 and got $36.90
