A circle is centered at the vertex of an angle, and the angle's rays subtend an arc that is 86 cm long. 1/360th of the circumference of the circle is 0.5 cm long. What is the measure of this angle in degrees?

A circle is centered at the vertex of an angle, and the angle's rays subtend an arc that is 86 cm long. The measure of this angle in degrees is 172°

From the given information:

The total circumference of the circle now will be:

= 360 × 0.5 cm

= 180 cm

However, if a total circumference of 180 cm is equivalent to an angle of 360°;

Then, an angle that subtends with 86 cm long will be:

= 172°

Therefore, the measure of this angle is 172°

Therefore the measure of this angle is

Step-by-step explanation:

Given, a circle is centered at the vertex of an angle  and the angle's rays subtend an arc that is 86 cm long.

0.5 cm arc make an angle

1 cm arc make an angle

86 cm arc make an angle

Therefore the measure of this angle is

0.02

step-by-step explanation:

time of 9 192 631 770 periods of the radiation corresponding to the transition between the 2 hyperfine levels of the ground state of the caesium 133 atom at 0 k (but other seconds are sometimes used in astronomy)

391.6 is the correct answer
