Chrissy is going to make a big painting on a piece of wood that is 4 fleet wide and has an area of 28 square feet. how long is the piece of wood

7 feet

Step-by-step explanation:

Assuming that the piece of painting is in the shape of a rectangle.

It is given that the width is 4 feet long and that the area is 28 feet².

We know that the Area of a rectangle is given by the formula length x width.

To find the length, we divide the area by the width.

Length = 28 ÷ 4 = 7 ft

So the length of the painting is 7 feet long.

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
