A triangular plot of land has one side along a straight road measuring 294 feet. a second side makes a 63degrees angle with the​
creativ13 [48]
The side across from the 63° angle is 299.5 ft and the side across from the 56° angle is 278.7 ft.

We will use the Law of Sines to solve this.  First, the angle across from the 63° angle:
sin 61/294 = sin 63/x

Cross multiply:
x*sin 61 = 294 sin 63

Divide by sin 61:
(x sin 61)/(sin 61) = (294 sin 63)/(sin 61)
x = 299.5

For the side across from the 56° angle:
sin 61/294 = sin 56/x

Cross multiply:
x*sin 61 = 294 sin 56

Divide both sides by sin 61:
(x sin 61)/(sin 61) = (294 sin 56)/(sin 61)
x = 278.7

What is the slope of the line through (-1,4) and (5,2)
butalik [34]

Answer:

Slope (m) = -\frac{1}{3}

Step-by-step explanation:

Use the following equation:

Slope (m) = \frac{y_2 - y_1}{x_2 - x_1}

Let:

(x_1 , y_1) = (-1 , 4)\\(x_2 , y_2) = (5 , 2)

Plug in the corresponding numbers to the corresponding variables:

m = \frac{2 - 4}{5 - (-1)} = \frac{2 - 4}{5 + 1} = \frac{-2}{6}

Simplify. Divide common factors from both the numerator and denominator:

\frac{(-\frac{2}{6})}{\frac{2}{2} } = -\frac{1}{3}

-\frac{1}{3} is your answer.
