For large parties at a seafood restaurant, a tip of 18% is automatically included on the bill. Jerome’s family went out for his grandmother’s 75th birthday. Their bill came to $268.21 before tip. Calculate the amount of tip that will be charged and the total amount after tip. Round to the nearest cent if necessary .

tip=48.28  

total cost =316.49

Step-by-step explanation:

tip = 48.28

Total + tip= 316.49

(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
