9514 1404 393

  74.8 m²

Step-by-step explanation:

The hint is usually a good place to start.

  A = (1/2)(11 m)(15 m)sin(115°) ≈ 74.8 m²

Additional comment

As is often the case with over-specified triangle problems, the answer you get depends on how you work the problem. Here, the hint suggests you use the angle. If you use the three side lengths, you find the angle is 114.7° and the area is about 74.9 m².

step-by-step explanation:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
