Answer:

x = -6

Step-by-step explanation:

expand the brackets:

7x+28 + 6x-18 = 8x-24 - 2x-8

now, collect like terms:

13x + 10 = 6x -32 (subtract 6x from both sides)

7x + 10 = -32 (minus 10 from both sides)

7x = -42 (divide by 7)

x = -6

sub into the original formula to check

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°.
