At a real estate​ agency, an agent sold a house for ​$312,000. The commission rate is 4.5​% for the real estate agency and the commission rate for the agent is 25​% of the amount the real estate agency gets. How much did the agency make on the​ house? How much did the agent earn in​ commission?​

final answer is : )

(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
