Two rectangles were used to form the following figure. the dimensions of the interior angle are 8 and 13 inches. the dimensions of the exterior angle are 9 and 15 inches. what is the area of the shaded region in square inches?

31²

Step-by-step explanation:

To find the answer first multiply 9 by 15 to get 135. Now multiply 8 by 13 to get  104. Now subtract 104 from 135 to get 31² as your answer.

answer: ok

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
