Give the equation that you would use to solve for exterior angles. Solve for x.

X = 93

Step-by-step explanation:

Angles of a polygon = (n - 1)180

The above polygon is heptagon (with 6 sides)

(6-1) × 180

5×180 = 900

Add the given Angles and equate it to 900 (as gotten above)

4x + 3x + 47 + 93 + 46 + 62 = 900

7x + 248 = 900

Collect like term of the number

7x = 900-248

7x = 652

Divide both side by the coefficient of x

7x/7 =652/7

X = 93.1429

For the lines to be parallel, the slope must be the same

(y2 - y1) / (x2 - x1) = slope

(7- (-3)) / (b-2) = -2

-2 (b-2) = 10

-2b + 4 = 10

-2b = 6

b = -3
