I would appreciate it if someone could help answer this problem:)

Answer:

Sum of Interior Angles = 900°

One Interior Angle = 128.57°

Step-by-step explanation:

We know that the figure is a Heptagon (a 7 sided polygon), therefore;

→ As by the formula of (n - 2) * 180° we can find the sum of the interior angles;

=> (n - 2) * 180 = Sum of Interior Angles

=> (7 - 2) * 180 = Sum of Interior Angles

=> 5 * 180 = Sum of Interior Angles

=> <u>900° = Sum of Interior Angles</u>

Now that we know the sum of interior angles,

→ We can find 1 interior angle by dividing the sum by the number of sides in the polygon.

=> Sum of Interior Angles / n = One Interior Angle

=> 900 / 7 = One Interior Angle

=> <u>128.57° = One Interior Angle</u>

Hope this helps!

Write the equation of the line that passes throught the point (-4,-9) and has a slope of 1/2
Ray Of Light [21]

Answer: y = 1/2x - 7

<u>Data</u>

Point = (-4, -9)

slope = m = 1/2

<u>Process</u>

To solve this problem, use the formula slope- y-coordinate, substitute the values and simplify.

<u>Equation</u>

 y - y1 = m (x - x1)

       x1 = -4

       y1 = -9

<u>Substitution</u>

y + 9 = 1/2 (x + 4)

<u>Simplification</u>

 y + 9 = 1/2x + 4/2

  y = 1/2x + 2 - 9

<u>Answer</u>

y = 1/2x - 7
