Respuesta :

If two chords of a circle are congruent, then their intercepted arcs are congruent
7x-39 = 87
7x = 87 + 39
7x = 126
x = 126/7
x = 18

The value of X calculeted in the circle is equal to 18.

What is the 2 parallel lines?

Parallel lines are basically two straight lines that do not have a point in common. In other words, they are two lines that do not meet, but that necessarily have the same direction.

If two chords of a circle are paralles, then their intercepted arcs are congruent:

[tex]7x-39 = 87\\7x = 87 + 39\\7x = 126\\x = 126/7\\x = 18[/tex]
