Traci wants to buy rings that cost 50$ each. a jewler is offering a deal in which you buy 1 ring and get the 2nd for 25% off and the 3rd fo 50% off. the sales tax is 8%. traci will buy 3 rings. how much money will traci save using the deal instead of paying full price for all rings?

(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
