Please solve this question

List the angles of triangle ABC in order from least to greatest. A(-3,-2) B(3,6) C (8, -2).

Thank you for taking your time to solve this question.

use the distance formula, $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$, to determine the lengths of each side of the triangle. The smallest side is opposite the smallest angle ; largest side is opposite the largest angle.

... either that, or sketch the triangle on a set of x-y axes and use your calibrated eyeball.
