A customer at a hardware store bought nails that cost a penny each, hooks that cost a dime each, and electrical tape that cost a half-dollar a roll. If the customer spent exactly $5.00 (before tax was added) and purchased 100 items, how many of each item did she buy?

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
