Answer:
106 degrees
Step-by-step explanation:
Sides AB and CD are equal in length and sides AD and BC are parallel to each other. This tells us that angles B and C are equivalent. Knowing this, we can set up the following equation to solve for x:
Subtract both sides by 42
Subtract both sides by 2x
Divide both sides by 2
Now, to find angle ABC, or angle B, we can plug x back into its expression:
Therefore, the measure of angle ABC is 106 degrees.
I hope this helps!
as you should already know to get the inverse of any expression, we start off by doing a <u>quick switcheroo</u> on the variables, and then solve for "y".
