The domain of this function is x = all real numbers.

The two things that typically limit a domain are dividing by zero and taking the square root of a negative. Since neither of these functions or their composite have a square root or a denominator, then you must be able to use all real numbers.

A plot of land has been surveyed for a new housing development with borders AB, BC, DC, and DA. The plot of land is a right trap
sdas [7]

Answer:

m∠ABC = 119° and DC = 105 feet

Step-by-step explanation:

For better understanding of the solution see the attached figure of the trapezium ABCD :

m∠BCD = 61°

By using the property, Sum of interior opposite angles in a trapezium is supplementary ⇒ m∠BCD + m∠ABC = 180°

⇒ m∠ABC = 180° - 61°

⇒ m∠ABC = 119°

Now, to find length of DC,

Draw a perpendicular BE on CD ⇒ CD = DE + EC

AB = DE

⇒ DE = 80 feet

In ΔBEC, By using Pythagoras theorem

EC² = BC² - BE²

⇒ EC² = 65² - 60²

⇒ EC = 25 feet

Hence, DC = 80 + 25

                   = 105 feet
