Chase measured a line to be 8.9 inches long. If the actual length of the line is 9.5 inches, then what was the percent error of the measurement, to the nearest tenth of a percent?

10%

Step-by-step explanation:

In this question, we are asked to calculate the percentage error in a measurement.

This can be obtained by first getting the error involved. That is calculated by Subtracting the value calculated from the actual value. That is 9.5 - 8.9 = 0.6

The percentage error is thus 0.6/9.5 * 100 = 6%

The value is actually 10% to the nearest tenth of a percent

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
