<h2>Answer:</h2>

True

<h2>Step-by-step explanation:</h2>

In geometry, a chord is any line segment that join two points on a circle while a central angle a central angle is an angle between two radii in a circle. Two chords are congruent if they measure the same length and this occur if and only if the associated Central angles are congruent. To understand this, focus on the figures below. The lines in red are chords and A and B are central angles. The chords will be congruent if and only if the associated Central angles are congruent, that is, A = B.

True, two chords are congruent if and only if the associated central angles are congruent.

<h3>Further Explanation</h3>

A chord is a segment in which both endpoints lie on the circle.  One of the chord theorems states that two chords are congruent if and only if they are equidistant from the center.  This means that the radii (plural for radius) formed from each endpoint to the center will be congruent.

Each radius forms two sides of a triangle with each chord.  This means we have three sides of each triangle congruent; by the Side-Side-Side theorem, this means that both triangles are congruent.  Since the triangles are congruent, the corresponding angles in each triangle are congruent; this means that the central angles are congruent.

22. 15/100= 0.15. 0.15•64,000= 9,600. The answer is D.
23. 1,200-300= 9,000. 1,200+300= 15,000. 9,000/15,000= 3/5. 3/5= 0.6. 60% of the building is aboveground.
24. The patterson seems to be the y=18x and when you plug 7 in to the equation, you get 126, not 128, so D is the answer.

Solving for x...
\frac{1}{2} x+ \frac{1}{4} =  \frac{15}{16} &#10;

Times the \frac{1}{2} , both the numerator and denominator, by 8 to get the denominator to 16.
Times the \frac{1}{4} , both the numerator and denominator, by 4 to get the denominator to 16.

Then rewrite the problem, 
\frac{8}{16}x+ \frac{4}{16} =  \frac{15}{16}

now that the denominators are all the same, you can solve...
subtract the \frac{4}{16} from both sides

you should get \frac{8}{16} x =  \frac{11}{16}

Multiply both sides by 16 (it'll cancel both the 16 out making it go away)
     8x = 11

divide each side by 8 to have the x alone

     <u>8x</u> = <u>11
</u>      8      8 
<u>
</u> You should end with x = \frac{11}{8} or 1.375<u>

Find the unknown measures of the indicated angles.
Sever21 [200]
The angles of a triangle always equal to 180 degrees.

Knowing this, you can solve this by this equation

Angle A + Angle B + Angle C = 180

43 + 85 + Angle C = 180

Angle C = 180 - 43 - 85
Angle C = 52
