the sand in an hour glass drops at a constant rate of 2.5 cubic meters every second. the amount of sand drops , y , in cubic meters is a function of time , x , in seconds for the input values of 0, 2, and 6 , determine the matching outputs . graph the inputs of 0 , 2 and 6 ,and their corresponding outputs as ordered pairs , represented by points a , b , c respectively

(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

c.
