Step-by-step explanation:
Hello!
We can use the special binomial product formulas:
<h3>Simplify</h3>
The simplified form is 
80 is a good one to start with.
After that, you can move on to 83, 481, 1687, and 102,974,589 .
Answer:
<h2>DA is equal to <u>
25</u> or BA</h2>
Step-by-step explanation:
ABC
ADC
- Since we know that line CA is equal to line CA because of <em>reflexive property</em>
- Angle BAC and DAC are equal because of <em>definition of an angle bisector</em>
- Angle ABC and ADC are equal because of <em>definition of an angle bisector</em>
- 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>
- So, if BA is 25, and we know that BA is congruent to DA, this tells us that DA is 25
So in your circle their is a terminal point who is assigned by the value of P(x,y) and lies or determined by teh value of T=4pi/3. To get the coordinates of this terminal point first is to know what is the angle of the T and the answer is (-1/2, -sqrt(3)/2)
