Given parameters:
Number of sides of the regular body = 10
A decagon has 10 sides.
Unknown:
Sum of the measures of the interior angles = ?
Solution;
To find the sum of the interior angles of a decagon; use the expression below:
Sum of interior angles = (n - 2) x 180
where;
n = number of sides;
So,
Sum of interior angles = (10 - 2) x 180 = 1440°
The sum of interior angle of a decagon is 1440°
Point-Slope Form is y + 7 = - 4( x + 5)
Slope-Intercept Form is y = - 4x - 27
Parallel equations have the same slope. The point-slope formula is basically y minus the given y-coordinate of the ordered pair, set equal to the slope being distributed to x minus the given x-coordinate. (If that explanation was complicated, you can just google the formula.) In order to find the slope-intercept form, you can use the point slope form and plug in zero for x to find the y-value that would be your y-intercept.

Answer:
0.333333333
Step-by-step explanation:
12 * 0.333333333 = 4
Answer:
Exact form : y=4 , -6/5
Decimal form : y=4 , -1.2
Mixed Number form : y=4 , -1 1/5
Step-by-step explanation: Isolate the variable by dividing each side by factors that don't contain the variable.
