What is the answer, she explanation pls
Bingel [31]

Answer: OPTION D.

Step-by-step explanation:

First, it is important to know the definition of "Chord"  and "Arcs" in circles.

A Chord is defined as a segment that joins any two points of a circle.

An Arc is defined as portion of the circumference of a circle.

By definition:

1) If two chords of a circle are congruent (which means that they have equal measure), then their intercepted Arcs are also congruent.

2) If the Arcs are congruent, then they have congruent chords.

In this case, you know that the <em>Arc GH</em> and the <em>Arc JK</em> are congruent. Therefore, you can conclude that the <em>Chord GH</em> and the <em>Chord JK</em> are also congruent.

Then, knowing that:

GH=9\ units

You can determine that:

JK=9\ units

Can anybody help me solve this? You must solve for x first.
gavmur [86]

Answer:

ABC = 65

Step-by-step explanation:

The sum of the angles of a quadrilateral are 360

2x-15 + x + 2x-15 +x = 360

Combine like terms

6x -30 = 360

Add 30 to each side

6x -30 +30 = 360+30

6x= 390

Divide by 6

6x/6 = 390/6

x=65

We want angle ABC

ABC = x

ABC = 65
