That would be B, C and E.
A and D could be a rhombus.
3(-2) -(1) -3(-2)
= -6 -1 +6 = -1
c = 60
Step-by-step explanation:
A triangle is a figure that has sum of all angles equals to 180
i.e ,
Angle A + Angle B + Angle C = 180
60 degree + 60 degree + Angle C = 180
Angle C = 180 - 60 - 60
Angle C = 60
Answer:
C
