Right i saucily‘s triangle has an angle with measure a 45° if x represents measure of the third angle of the triangle what is x a/30° b/45° c/100° d/135°

A, b, c, and d have the coordinates (-8, 1), (-2, 4), (-3, -1), and (-6, 5), respectively. which sentence about the points is true? a. a, b, c, and d lie on the same line. b. and are perpendicular lines. c. and are parallel lines. d. and are intersecting lines but are not perpendicular. e. and are parallel lines.

How do i do this activity, is appreciated
