If an regular interior angle of a regular polygon is 140 degrees, how many sides does the polygon have and I need the work
1 answer:
Answer:
9 sides
Step-by-step explanation:
exterior angle + interior angle = 180° , so
exterior angle + 140° = 180° ( subtract 140° from both sides )
exterior angle = 40°
The sum of the exterior angles of a polygon = 360°
Dividing sum by the measure of 1 exterior angles gives number of sides
number of sides = = 9

y-intercept = 2
Equation of the line 't':
Step-by-step explanation:
Slope of a line passing through two points and
is represented by,
Slope 'm' =
Since line 't' is passing through two points (0, 2) and (8, -4),
Slope of the line 't' =
m =
m =
Since y-intercept of a line is the value of 'y' for x = 0 [from point (0, 2) lying on this line]
Therefore, Y-intercept of line 't' = 2
Slope intercept of an equation is,
y = mx + b
where m = slope of the line
b = y-intercept
Therefore, equation of the line 't' will be,
