1. Your parents took your family out to dinner. Your parents want to give the waiter a 20% tip. If the amount of the dinner was $42.00, how much is the tip?

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

(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

it would open into a square depending on the type of envelope i’m not sure about the second part
