Who is the Centre of the circle such that angle AOC is equal to 130 degree then angle ABC is equal to?
∠ABC = 115°
What is the angle of AOC?
AOCB is a quadrilateral in a circle with center O, angle AOC = 130 degrees. A circle is a closed, two-dimensional curved shape with no corners or edges.
What is the angle degree of a circle?
A circle is divided into 360 equal degrees, so that a right angle is 90°. For the time being, we’ll only consider angles between 0° and 360°, but later, in the section on trigonometric functions, we’ll consider angles greater than 360° and negative angles.
What is the longest chord of a circle?
diameter
A chord that passes through the center of a circle is called a diameter and is the longest chord of that specific circle.
How do you measure AOC?
If B is in the interior of angle AOC, then the measure of AOB + the measure of BOC = the measure of AOC. If two angles are complementary to the same angle (or to congruent angles) then the two angles are congruent.
What is an angle with 0 degrees?
An angle with a measure of zero degrees is called a zero angle. The angle they create has been shrunk from its original measure to zero degrees. The angle that is now formed has a measure of zero degrees.
Is a circle 360 degrees?
A full circle is 360 degrees because the Babylonians used the sexagesimal system. It also represents the number of days a year and also because 360 is highly composite.
Which is the chord on circle O?
The figure below depicts a circle and its chord. In the given circle with ‘O’ as the center, AB represents the diameter of the circle (longest chord), ‘OE’ denotes the radius of the circle and CD represents a chord of the circle.
What is the centre of the circle if ∠AOC = 130o?
In given fig. O is centre of the circle if ∠AOC = 130o then find ∠ABC. Was this answer helpful?
What is the centre of a circle with Bao = 30^∘?
O is the centre of the circle, find AOC , given BAO = 30^∘ and BCO = 40^∘ . O is the centre of the circle, find ∠AOC, given ∠BAO=30 ∘ and ∠BCO=40 ∘. So option B is the right answer.
How do you find ADC on a circle with centre O?
1. In Fig. 10.36, A,B and C are three points on a circle with centre O such that BOC = 30° and AOB = 60°. If D is a point on the circle other than the arc ABC, find ADC.
