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

General Formulas and Concepts:
<u>Algebra I</u>
- Coordinates (x, y)
- Reading a Cartesian (Rectangular) plane
- Solving systems of equations by graphing
Step-by-step explanation:
Where the 2 lines intersect will be the solution set to the systems of equations.
If the lines are parallel, they will have no solution.
If the lines are the same, they will have infinite amount of solutions.
Answer:
150ft²
Step-by-step explanation:
surface area = (2×½×8×3)+(8+5+5)×7
= 24+126
= 159 ft²
