Row 3 Row 4 b. How many seats are in Row 15? C. Each ticket costs $ 40.If every seat in the first 10 rows is filled, what is the total revenue from those seats? d. An extra chair is added to each row. Write the new rule for the arithmetic sequence and find the new total revenue from the first 10 rows.

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
