How does one calculate arc length when given the radius and angle measure in degrees?
To find the arc length given the radius and angle measure in degrees, you must first convert the angle from degrees to radians, using the formula: Degrees = Radians X (pi/180). Then take the radians and the radius that you are given, and put them into the formula of Q = (a/r) where Q is the angle in radians, a is the arc length, and r is the radius. When you have this, simple multiply both sides by the radius to isolate the a. Once you do this, you have your answer.
Calculate the number of sides of a regular polygon whose exterior angles are each , a=9°, b=30° c=24° d=22.5°?
To calculate the number of sides of a regular polygon, we can use the formula: Number of sides (n) = 360° / Exterior angle Let's find the number of sides for each given exterior angle: a = 9°: n_a = 360° / 9° = 40 sides b = 30°: n_b = 360° / 30° = 12 sides c = 24°: n_c = 360° / 24° = 15 sides d = 22.5°: n_d = 360° / 22.5° = 16 sides So, the number of sides for each given exterior angle are: a = 40 sides b = 12 sides c = 15 sides d = 16 sides
What is the rule to get the number of sides of a regular polygon when given the interior angle?
180-interior angle = exterior angle 360/exterior angle = number of sides
What is the formula used to calculate the number of sides in a polygon using its angle measures?
Let S be the sum of the measures of all the interior angles, in degrees. Then the number of sides is S/180 + 2.
How do you calculate the number of sides in a polygon for an exterior angle of 10 degrees?
In general you cannot. Only if the shape in question is a regular polygon, then there are 360/10 = 36 sides.
Number of triangles in a 32 side polygon?
gghg a regular polygon has a 32 sides. calculate the size of each interior angle.
How do you work out the number of sides in a regular polygon that has an exterior angle?
With a regular polygon: 360/exterior angle = number of sides
How do you find an angle in quadrangle without a protractor?
Measure the two sides adjacent to the angle and the diagonal at the far ends of these sides. Then use the cosine rule to calculate the angle.
how many sides does a regular polygon have if the exterior angle is 15?
by the number of sides, 'n' of that particular polygon. by the exterior angle. Therefore, the number of sides of the polygon is 24 sides.
Give the formulas for finding the number of sides of a regular polygon when given the measure of an interior angle?
180-interior angle = exterior angle 360/exterior angle = number of sides
What is the number of sides a regular polygon have with an interior angle of 174?
Interior angle = 174 so exterior angle = 180-174 = 6 degrees. Therefore, number of sides = 360/exterior angle = 360/6 = 60 sides.
How to calculate the sides of a triangle given the degree of an angle and one side?
The measure of only one angle and one side is not sufficient to calculate the lengths of the sides of a triangle. If you have one more angle or one more side you can use the sine rule.
