Jan is saving up to buy a skateboard she already has 30 dollars saved up witch it 20 percent of the total price. how much does the skateboard

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

b.   e = 7.5h

hope this , lovely!

any of them that add up to 180 degrees.
