Correct answer is : Area of triangle is 
Solution:-
We can do it in 2 methods.
Method 1:-
Given that AB=6, BC=10 and m∠B = 120
Then area of triangle = 
Let us assume AB is base and D is an altitude from C onto AB.
Then sin(60)= 
CD = BC sin(60)
Hence height = 
= 
Hence area of ΔABC = 
sq.units
Method2:-
Area of triangle = 
Here a= BC=10, c=AB=6.
Hence area of triangle = 
sq.units
15x + 30y = -10....reduce by dividing by 5
3x + 6y = -2...same as first equation...same line ..means infinite solutions
Answer:
The shopper should but the 6 pcs pack because its cheaper.
Step-by-step explanation:
6-pcs pack = $2.10
hot dogs needed = 48
number of 6 pcs = 48 divided 6 = 8
