Which statement is always true? a. a cross section parallel to the base of a right rectangular prism is a square. b. a cross section perpendicular to the base of a right rectangular prism is congruent to the base. c. a cross section parallel to the base of a right rectangular prism is congruent to the base. d. a cross section perpendicular to the base of a right rectangular prism has the same dimensions as the base.

I believe the answer is D.

Step-by-step explanation:

The answer is C

Step-by-step explanation:

Because when we cut through any part of the prism parallel to the base, the shape of the cross section is the same as the base.

answer: it is d

step-by-step explanation:

(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
