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
