Okay so you do not really need the circle equation. if you make a triangle with it's x length as 3 and it's y length as 4, you will be able to find the third length. Do Pythagorean theorem to find the hypotenuse.
the hypotenuse will be five after you calculate it.
sin is opposite over hypotenuse or Y over R
so... the sin is 4/5
make sure you know what quadrant your triangle is in for the negatives
It’s A. The other ones don’t work.
Answer:
A is your answer
Step-by-step explanation:
The points have the same x-coordinate, so they lie on a horizontal line. The distance between them is the difference between their y-coordinates.
2.5 - 1.4 = 1.1
The distance between the two points is 1.1
