Nico is hitting golf balls at a driving range he uses the expression 50-10 to determine the number of balls he has left to hit what could this expression mean? check all that apply

You need to show us all of the options that are given because the questions states to 'check all that apply'.

Step-by-step explanation:

50-10 means that has 40 golf balls left to hit.

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
