Question

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?

Answer 1

Answer:

Therefore the measure of this angle is $=(\frac{43}{90} )^\circ$

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 $\frac{1}{360}$

1 cm arc make an angle $\frac{1}{360\times 0.5}$

86 cm arc make an angle $\frac{86}{360\times 0.5}$

                                         $=(\frac{43}{90} )^\circ$

Therefore the measure of this angle is $=(\frac{43}{90} )^\circ$
