Match the equation with the step needed to solve it.

subtract 1 2m - 1 = 3m
subtract 2 2m = 1 + m
subtract m m - 1 = 2
add 2 2 + m = 3
subtract 2m -2 + m = 1
add 1 3 = 1 + m

(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

it is x=-4
