Abuilder is trying to level out some ground with a front-end loader. he picks up some excess dirt at (7, 18) and then maneuvers through the job site along the vectors angleleft −3, 0 angleright, angleleft 7, 3 angleright, angleleft 3, 10 angleright to get to the spot to unload the dirt. find the coordinates of the unloading point. find a single vector from the loading point to the unloading point.

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
