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.

Answer:
The product is positive, thus it is
Step-by-step explanation:
The full question in proper notation is:
"Find the product. If the result is negative, enter "-". If the result is positive, enter "+".
"
We have to work with it using Order of operations know as well as PEMDAS, thus expression inside parenthesis go first and exponents.
On this expression we have to work with exponents
Thus we get
Lastly we can work with multiplication and remembering that the multiplication of two negative signs becomes positive.
So the final simplified expression is
