120 sides.
Sum of exterior angles of a polygon = 360o (= number_of_sides x exterior_angle for a regular polygon).
For 177o interior angle, exterior angle = 180o - 177o = 3o.
Thus:
360o = numb_of_sides x 3o
=> number_of_sides = 360o / 3o
= 120

How many sides a polygon have with an angle 30?
Smallest possible interior angle of regular polygon is 60 degrees (triangle). The greater the number of sides, the greater each interior angle. If exterior angle is 30 degrees, the polygon has 12 sides.
How many sides does the polygon have if it has an interior angle which is 3 times the exterior angle?
Providing that it is a regular polygon it will have 8 sides.
How many sides does a regular polygon have if the measure of each interior angle is equal to 172 degress?
How many sides does a regular polygon have if the measure of each interior angle is equal to 172 degress ?
In a regular polygon the ratio of an exterior angle to the measure of an interior angle is 2 to13 how many sides does the polygon have?
Interior angle 156 degrees Exterior angle 24 degrees 360/24 = 15 sides
How many sides does a regular polygon have if the measure of one interior angle is 150?
if the interior angle is 150 the exterior angle equals 30. since exterior angle equals 360/ by number of sides the number of sides equals 360/30 which equal 12
How many side has a polygon got if the interior angle is 162 degrees?
Assuming every interior angle is the same, and they're all 162 degrees, the shape would have 20 sides.
How many sides does the polygon have if the interior angle is 6660 degrees?
how many sides does the polygon have is the interior angle is 6660 degrees? important please tell me...
How many sides does a regular polygon have if the interior angle is 176o?
If each interior angle measures 176 degrees then it will have 90 sides
How many sides are in a regular polygon with an interior angle of 172.5?
48 sides A formula for finding the number of sides of a regular polygon given an interior angle: 360/(180-angle)=sides
How many sides does a regular polygon have if the measure of one interior angles is 144?
interior angle = (sides - 2) * 180 / sides sides * interior angle = 180 * sides - 360 sides * (interior angle - 180) = -360 sides = -360 / (interior angle - 180) sides = 360 / (180 - interior angle) So, for 144 degrees: sides = 360 / 36 = 10
How many sides does a regular polygon have if the measures of the interior angle is 174 degrees?
If each interior angle measures 174 degrees then it will have 60 sides
How many sides would there on a polygon with an interior angle of 60?
If each interior angle is 60 degrees then it will have 3 sides in the form of an equilateral triangle.
How many sides does polygon have if the interior angle measures 8820?
51 sides
How many sides does a regular polygon have if the measure of the angle is 162?
Interior angle 162 Exterior angle 18 It will have 20 sides
How many sides would a regular polygon have with an interior angle of 178 degrees?
If interior angle is 178o then the exterior angle = 180 - 178 = 2o So the number of sides = 360 / 2 = 180 sides.
How many sides does a regular polygon have its angle is 160?
If each interior angle is 160 degrees then it will have 18 sides
How many degrees does a polygon with 30 sides have?
A polygon with 30 sides has a total interior angle measurement of 5040o, with each interior angle measuring 168o.
