Question

A polygon ABCDE in which the measures of the interior angles are (6x)°, (4x+13)°, (x+9)°, (2x−8)°, and (4x−1)°.

SOLVED

Answer 1

Solution

slope = 2

Explanation:

calculate the slope m using the slope formula

m = \frac{rise}{run}

run

rise

= \frac{y_{2}-y_{1} }{x_{2}-x_{1} }

x

−x

y

−y

with (x₁, y₁ ) = (- 1, - 5) and (x₂, y₂ ) = (2, 1) ← 2 points on the line

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

2−(−1)

1−(−5)

= \frac{1+5}{2+1}

2+1

1+5

= \frac{6}{3}

= 2
