Option C is your answer ( x = 6 and y = 3)

Step-by-step explanation:

For a parallelogram opposites are parallel and are equal so we use this information to calculate the value of x and y so here goes,

For x :

Lets take the sides AB and DC both are parallel and since it's a parallelogram they must be equal so we equate both the sides like this ,

we found the value of x = 6 now we need the value of y

For y :

We take the sides AD and BC since they are parallel and opposites are equal so ,

so now the value of y = 3 so Option C is your answer

a box 3 3/4 feet long or 4+ feet.

step-by-step explanation:

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
