Answer:
Hey there!
They are congruent by AAS, where two angles and one side is congruent.
Hope this helps :)
degree to radian = angle in degree * pi/180
rad = 150 * pi/180 = 2.618 radians
Use formula: an = a1 * r^(n-1)
a1 = 2, r = -2
a12 = 2 * -2^(12-1)
a12 = 2 * -2^11
a12 = 2 * -2048
a12 = -4096
Solution: -4096
