Answer:
Step-by-step explanation:
Supplementary angles are angles that add up to 180. Normally, they are supplementary because they lie adjacent to one another on a line.
In this base, b is supplementary to 81! Meaning, to find b we can simply subtract 81 from 180.

Answer:
D.
Step-by-step explanation:
To rewrite a mixed number as an improper fraction, first, multiply the whole number by the denominator.
Then, add this number to the numerator.
This number is now the numerator of the fraction. The denominator stays the same.
I hope this helps!
This is a proof that the angles in a triangle equal 180°:
The top
line (that touches the top of the triangle) is
running parallel
to the base of the triangle.
So:
<span> <span>angles A are the same </span> <span>angles B are the same </span> </span>
And you can easily see that A + C + B does a complete rotation from one side of the straight line to the other, or <span>180°</span>
