Answer:
15 (rounded) 14.7 (not rounded)
Step-by-step explanation:
Answer:
The answers are that the x-coordinate is 3, the y-coordinate is 4 and it is in quadrant I
Step-by-step explanation:
To find these answers, start by solving the system. We can do this by multiplying the second equation by 2 and adding them together.
8x + 6y = 48
4x - 6y = -12
-------------------
12x = 36
x = 3
Next, find the y value by plugging in the x value to either equation and solving.
2x - 3y = -6
2(3) - 3y = -6
6 - 3y = -6
-3y = -12
y = 4
Area of the triangle:
A = 1/2 · c · b · sin A =
= 1/2 · 30 · 14 · 0.766 ≈ 160.87 ft²
