12 2. when you measure the length of an object to the eighth of an inch and again to the fourth of an inch, which measurement is more precise? explain your answer.

3. use the measurements in question 2 above to explain this statement: “when you calculate with measurements, your answer shouldn’t be any more precise than the least precise measurement.” don't answer q2

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
