Find b and c, with showing your work.

AB = 90 degrees

AC = 60 degrees

Step-by-step explanation:

Since every triangles angles equal to 180 you first subtract 30 from 180 which is 150 degrees. You can see there is a square around a vertex which means that angle is 90 degrees. Now subtract 90 from 150 which is 60 degrees. So the last angle is 60 degrees.

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

step-by-step explanation:

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser
