Answer:
<em>x² + y² = 841 </em>
Step-by-step explanation:
Midpoint of diameter is a center of a circle.
Coordinates of midpoint are
( 
, 
)
( 
, 
)
( 
, 
)
d = 
Equation of a circle with center at (h, k) and radius "r" is (x - h)² + (y - k)² = r²
~~~~~~~~~~
C(20, 21)
D(- 20, 21)
( 
, 
) = (0, 0)
d = 
= √3364 = 58
r = 
= 29
x² + y² = 29²
<em>x² + y² = 841</em>

Answer:
Then the best way to phrase it would be to jump right into the question without I need your help, because saying so makes it sound as though you have more of an urgent, sensitive, personal problem than a simple question or two (they might be a bit taken aback by the phrase).
However, if you have several questions (let's say more than 2), or if you just want to sound a bit more polite, you could preface the content with a phrase like I was wondering I you might be able to answer a few questions of mine, or, I have a few questions that I was hoping you might be able to help me with.
Answer:
f(2)=9
Step-by-step explanation:
The missing justification in Julia's angle proof is; Corresponding Angles Theorem
<h3>What is the angle theorem used?</h3>
We know that m∠AGE ≅ m∠HGB because they have congruent angles and are vertical angles.
Similarly, m∠HGB ≅ m∠CHE are alternate interior angles because two congruent angles on the inner side of the parallel lines are formed by a transversal.
In the diagram, m∠AGE ≅ m∠CHE would have to be corresponding Angles Theorem because parallel lines cut by a transversal would create congruent corresponding angles. That means a pair of angles on the same side of one of two lines that is cut by a transversal and on the same side of the transversal.
