What is DA equal to? Brainiest if correct and please show your answer.
Naddik [55]

Answer:

<h2>DA is equal to <u>25</u> or BA</h2>

Step-by-step explanation:

ABC

ADC

  1. Since we know that line CA is equal to line CA because of <em>reflexive property</em>
  2. Angle BAC and DAC are equal because of <em>definition of an angle bisector</em>
  3. Angle ABC and ADC are equal because of <em>definition of an angle bisector</em>
  4. This will give us <em>ASA</em>, proving to us that all sides and angles are congruent <u>(this was already given to us)</u>
  5. So, if BA is 25, and we know that BA is congruent to DA, this tells us that DA is 25

What is the radius of the circle defined by x2 + 2x + y2 + 6y − 39 = 0?<br> 49<br> 9<br> 7<br> 81
Bond [772]

radius = 7

the equation of a circle in standard form is

(x-a)² + (y-b)² = r²

where (a, b) are the coordinates of the centre and r is the radius

To obtain this form ' complete the square ' on both the x and y terms

x² + 2(1)x + 1 + y² + 2(3)y + 9  = 39 + 1 + 9

(x+1)² + (y+3)² = 49 ← in standard form

with centre (1, 3) and r = √49 = 7
