9. The surface area of a rectangular prism is the sum of the ain areas of its faces. Study the six faces of a rectangular prism.
Notice how the opposite faces on the prism are congruent:
front and back, top and bottom, and left and right sides. Use
the net to help you fill in the numbers needed to find the
surface area of the rectangular prism.

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
