Suzy spent 6 7/8 days working on her english paper, 3 1/6 days doing her science project, and 1 1/2 days studying for her math test. how many days more did suzy spend on her english paper and math test than on her science project?

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

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
