Please help find the amount of interior angles in the shape.

gladu [14]

The polygon has 11 sides.

The measure each interior angle is 147.272°.

Solution:

The given shape is a regular polygon.

(a) Number of sides of the polygon = 11

The polygon has 11 sides.

(b) To find the measure of each interior angle:

Each interior angle of a regular polygon

$$=\frac{(n-2) \times 180^{\circ}}{n}$

$$=\frac{(11-2) \times 180^{\circ}}{11}$

$$=\frac{9 \times 180^{\circ}}{11}$

$=147.272^\circ$

The measure each interior angle is 147.272°.

The equation of the line that contains the points (-8, 1) and (0, -5) is

posledela

Answer:

y = -3/4x -5 (G)

Step-by-step explanation:

Find the slope by using the slope formula. (It's hard to format here so look it up)

Basically, it is y2 - y1/x2 - x1

-5 - 1/ 0 + 8

-6/8 = -3/4

The slope is -3/4.

Plug in for y = mx + b

y (y coordinate) = -5

x (x coordinate) = 0

slope (m) = -3/4

-5 = -3/4(0) + b

-5 = 0 + b

b = -5

y = -3/4x -5
