What is the relation between the arc length and angle for a sector of a circle?
A sector is the area enclosed by two radii of a circle and their intercepted arc, and the angle that is formed by these radii, is called a central angle. A central angle is measured by its intercepted arc. It has the same number of degrees as the arc it intercepts. For example, a central angle which is a right angle intercepts a 90 degrees arc; a 30 degrees central angle intercepts a 30 degrees arc, and a central angle which is a straight angle intercepts a semicircle of 180 degrees. Whereas, an inscribed angle is an angle whose vertex is on the circle and whose sides are chords. An inscribed angle is also measured by its intercepted arc. But, it has one half of the number of degrees of the arc it intercepts. For example, an inscribed angle which is a right angle intercepts a 180 degrees arc. So, we can say that an angle inscribed in a semicircle is a right angle; a 30 degrees inscribed angle intercepts a 60 degrees arc. In the same or congruent circles, congruent inscribed angles have congruent intercepted arcs.
How do you find the angle with the radius and the arc length?
The arc length divided by the radius is the angle in radians. To convert radians to degrees, multiply by (180/pi).
What is the height of a moutain when from the top of a tower which is 180 meters high the angle of elevation is 25.3 degrees and its bottom angle of elevation is 26.42 degrees?
Using the sine rules in trigonometry the height of the mountain works out as 3704 meters in height to the nearest whole number.
What is -- To the nearest degree what is the measure of each exterior angle of a regular octagon?
Each exterior angle of a regular octagon is 360/8 = 45 degrees
How do you calculate the angle for length 2350 and height 500?
Find the angle whose tangent is 500/2350, about 12 degrees
The tangent of an angle is 0.8 what is the measure of the angle to the nearest tenth?
tan-1(0.8) = 38.65980825 degrees or 38.7 degrees to the nearest tenth.
What is the length of BC in this triangle angle BAC equals 40 degrees and angle ABC equals 50 degrees and angle BCA equals 90 degrees .?
In order to find length BC the length of AC or length of the hypotenuse must be given
What is the area of a triangel to the nearest whole number if A52 degrees 63 degrees and c 8?
The answer will depend on which angle is 63 degrees, and the measurement units used for c.
How many degrees are in a supplementary angle?
A supplementary angle is a 180-degree angle minus the number of degrees in the given angle.
Which triangle has an angle that measures 45 and 90 degrees?
Well, it doesn't exactly have "an angle that measures 45 and 90 degrees". It has one angle that measures 45 degrees, and another angle that measures 90 degrees. That's an isosceles right triangle. The third angle is also 45 degrees, and the length of each leg is 70.7% of the length of the hypotenuse. .
The number of degrees of an angle?
The answer depends on the angle.
What is the angle in nearest degrees created by the minute hand and the hour hand at 515?
60 degrees
What is the longest length of a triangle if its shortest length is 3.6cm when two of its angles are 37.25 degrees and 48.4 degrees?
Largest angle: 93.25 degrees Shortest angle: 37.25 degrees Shortest length: 3.6cm Longest length: 3.6*sin(94.35)/sin(37.25) = 5.93cm to two decimal places
The tangent of an angle is 0.8. What is the measure of the angle to the nearest tenth?
It is: tan^-1*(0.8) = 38.7 degrees
The number of degrees in a angle?
It is a measure of the size of the angle.
What is the length of the minor arc if the angle is 30 degrees?
It's 0.524 of the length of the radius.
Who to arc length Radius of the circle 4756 and angle 45deg find arc length?
(arc length)/circumference=(measure of central angle)/(360 degrees) (arc length)/(2pi*4756)=(45 degrees)/(360 degrees) (arc length)/(9512pi)=45/360 (arc length)=(9512pi)/8 (arc length)=1189pi, which is approximately 3735.3536651
