Sanaiah can work at most 20 hours next week, but she needs to earn at least $200. Her babysitting job pays $12.50 an hour and her dog walking job pays $10 an hour. Identify the variables and then write a system of equations to represent the constraints on Sanaih's work time and income. Remember to include common sense constraints. You will have 4 separate inequalities for your answer.

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
