2. Find the sum of the digits of each multiple of 9 below. Sum of digits
9
1 + 8 = 9
9.1 = 9
9.2 = 18
9.3 = 27
9.4 = 36
9.5 = 45
9.6 = 54
9.7 = 63
9.8 = 72
9.9 = 81
Describe a pattern. (Do you think it will continue?)

(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

what is the rest of the question? ?

i'm a sophomore in connections, i'd recommend checking on jishka.com they have a large range of questions and answers from our school.
