Match the vocabulary word with the correct definition.

supplementary angles-either of two angles whose sum is 180°.

transformation- a change made to a shape or object

scalene triangle- a triangle with no equal sides

similar triangles-the same shape but not necessarily the same size

semi-circle- and arc measure up to 180 degrees

I hope this is good enough:

(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

if you was gonna solve for a, a is a   < -12
