Chip has 50 feet of fishing line. he cut it into 10 equal pieces. how long was each piece of fishing line?

5 feet long

Step-by-step explanation:

50 feet of line

= 5 feet per piece

   10 pieces

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
