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

There are 64 singers in the choir.The tenors and sopranos are in separate rows.There are 8 singers in each row.There are 4 rows

4 rows because 4 times 8 equals 32, so then there are only 32 singers left. 64-32=32, and once again 4 times 8 equals 32.
