Answer:
yes, this is a triangle. It is a right triangle
Step-by-step explanation:
The three angles of a triangle add to 180 degrees
27+90+63 = 180
180=180
This is true so it is a triangle.
Because one of the angles is 90 degrees, it is a special type of triangle called a right triangle.
-6(3i)(-2i)= -36
2(3-I)(-2+4i)= -4 + 28i
