How do you find tangents?
draw a line perpendicular to the radius which was set at a specific number of degrees from zeroin the circle
How do you find the arc length of a circle that has an inscribed polygon?
What do you mean by "arc length of a circle"? If you mean the arc length between two adjacent vertices of the inscribed polygon, then: If the polygon is irregular then the arc length between adjacent vertices of the polygon will vary and it is impossible to calculate and the angle between the radii must be measured from the diagram using a protractor if the angle is not marked. The angle is a fraction of a whole turn (which is 360° or 2π radians) which can be multiplied by the circumference of the circle to find the arc length between the radii: arc_length = 2πradius × angle/angle_of_full_turn → arc_length = 2πradius × angle_in_degrees/360° or arc_length = 2πradius × angle_in_radians/2π = radius × angle_in_radians If there is a regular polygon inscribed in a circle, then there will be a constant angle between the radii of the circle between the adjacent vertices of the polygon and each arc between adjacent vertices will be the same length; assuming you know the radius of the circle, the arc length is thus one number_of_sides_th of the circumference of the circle, namely: arc_length_between_adjacent_vertices_of_inscribed_regular_polygon = 2πradius ÷ number_of_sides
How do you find the Major arc in a circle?

How do you find the measure of an interior angle in a quadrilateral inscibed in a circle?
There is no specific limitation on any one angle of an inscribed quadrilateral.
How do you find tangents?
draw a line perpendicular to the radius which was set at a specific number of degrees from zeroin the circle
How do you find the angle of a triangle within a circle segment?
To find the angle of a triangle within a circle segment, you first need to determine the central angle of the circle segment. Then, you can use the properties of triangles inscribed in circles to find the angle. The angle of the triangle within the circle segment will be half the measure of the central angle.
How do you find area and circumfrence of a circle?
It depends on what information you have: radius, diameter, lengths of tangents from a point outside the circle, length of chord and its distance from the centre, etc. Also, the term is circumference, not circumfrence.
If you only have the central angle of a circle can you find the radius?
If "the angle" means the angle between two radii at the centre, the answer is no. You need to know the circumference first. Then use radius = circumference divided by 2 x pi.

How can you find the angle of a sector in a circle?
Multiply ( pi R2 ) by [ (angle included in the sector) / 360 ].
How do you find the measure of an angle corresponding to the percent of a circle?

A sector of a circle has a central angle of 50 and an area of 605 cm2 Find the radius of the circle?
If the sector of a circle has a central angle of 50 and an area of 605 cm2, the radius is: 37.24 cm
How do you find the central angle in a circe?
The central angle of the circle is the angle around a point and so, be definition, it must be 360 degrees.
How do you work out a right angle triangle where you know the opposite side and the adjacent side to get the opposite angle?
The ratio of the opposite side over the adjacent side is called the tangent.Expressing the fraction (opposite/adjacent) as a decimal, you can find the angle by looking in a table of values for the tangents of various angles.
How do you find a missing angle measure of a circle?
It depends on what information is available.
