Question

Which conditional has the same truth value as its converse?

A: If an angle has a measure of 80°, then it is acute.
B: If x – 17 = 4, then x = 21.
C: If x = 7, then |x| = 7
D: If a figure is a square, then it has four sides.

Answer 1

B: If x – 17 = 4, then x = 21. is your best answer

This is because, if we flip it

if x = 21 then x - 17 = 4 (which is still true)

hope this helps
