are alternate exterior angles
The statement is False
Because, ∠B and the angle marked
are corresponding angles
case C)
because it is a vertical angle to the angle marked 
The statement is True
we know that
------> by vertical angles
case D) ∠B and ∠C are supplementary angles
The statement is False
we know that
---> the sum is less than
case E) 
The statement is True
we know that

and remember that

so
substitute

Answer= 2.6
Method= 1/3 of (of = x on calculator) 23= 7.6
