before he leaves for the airport Jorge weighs his luggage. he has a case a laptop computer and a backpack with total weight 19.2 kg. 2/3 of the 19.2 kg is the weight of the case and 3/5 of the remainder is the weight of his laptop, how much does the backpack weight?

(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

the answer is a beach is the best place to be

thus, the first answer choice, y = sec x, is the correct one
