Answer:

A=28.7\ ft^{2}

Step-by-step explanation:

we know that

The formula to calculate the area of a triangle applying the law of sines is equal to

A=\frac{1}{2}(a)(b)sin(C)

we have

a=14\ ft

b=12\ ft

C=20\°

substitute in the formula

A=\frac{1}{2}(14)(12)sin(20\°)

A=28.7\ ft^{2}

What is the slope of the line passing through the points (-3,4) and (4,-1)
Serhud [2]

Answer:

slope = - \frac{5}{7}

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 3, 4) and (x₂, y₂ ) = (4, - 1)

m = \frac{-1-4}{4+3} = - \frac{5}{7}
