Answer:

Slope (m) = \frac{y}{x} = \frac{3}{1} =3

Step-by-step explanation:

Slope (m) = \frac{y}{x} = \frac{3}{1} =3

0 = arctan(\frac{y}{x}) + 180^o = 251.56505117708^o

X = -4 – -2 = -2

Y = 4 – 10 = -6

Distance (d) = \sqrt{x^2+y^2}=\sqrt{40} = 6.3245553203368

Equation of the line:

y = 3x + 16

When x=0, y = 16

When y=0, x = -5.3333333333333

Find the value of X<br>​
arsen [322]

Answer:

x = 118

Step-by-step explanation:

1. All the angles in a pentagon add up to 540, so to find the value of x, we can use this equation x + 122 + 103 + 98 + 99 = 540.

2. (Solving)

Step One: Simplify both sides of the equation by adding like terms.

  • (x) + (122 + 103 + 98 + 99) = 540
  • x + 422 = 540

Step Two: Subtract 422 from both sides.

  • x + 422 - 422 = 540 - 422
  • x = 18
