If three central angles measures 65, 87, and 112, find the measure of the fourth central angle.
You find the arc measure and then you divide it in half to find the inscribed angle
Would you mean an angle? Then you'd measure it with a protractor.
Well, in degrees, the arc is congruent to its central angle. If the radius is given, however, just find the circumference of the circle (C=πd). Then, take the measure of the central angle, and divide that by 360 degrees. Multiply the circumference by the dividend, and you will get the arc length. This works because it is a proportion. Circumference:Arc length::Total degrees in triangle:Arc's central angle. Hope that helped. :D
If the central angle is 70 and the radius is 8cm, how do you find out the chord lenght?
the measure of the inscribed angle is______ its corresponding central angle
If three central angles measures 65, 87, and 112, find the measure of the fourth central angle.
You also need the measure of the central angle because arc length/2pi*r=measure of central angle/360.
the measure of a minor arc equals the measure of the central angle that intercepts it.
An arc can be measured either in degree or in unit length. An arc is a portion of the circumference of the circle which is determined by the size of its corresponding central angle. We create a proportion that compares the arc to the whole circle first in degree measure and then in unit length. (measure of central angle/360 degrees) = (arc length/circumference) arc length = (measure of central angle/360 degrees)(circumference) But, maybe the angle that determines the arc in your problem is not a central angle. In such a case, find the arc measure in degree, and then write the proportion to find the arc length.

If you absolutely needed to measure an angle to find out its degree measure, you would use a protractor.
suck this dudck.
there are 180 degrees in a striaght line
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.
-- Circumference of the circle = (pi) x (radius) -- length of the intercepted arc/circumference = degree measure of the central angle/360 degrees
You find the arc measure and then you divide it in half to find the inscribed angle
