You can tell if they're similar if they:
1) Have two of the same angles
2) If two pairs of corresponding angles in a pair of triangles are congruent.
3) If they are the same shape
According to the graph, the answer is C. 150
Unfortunately there is no picture, im sorry
(x - h)^2 + (y - k)^2 = r^2
h = -2
k = -2
r = 6
(x - (-2))^2 + (y - (-2))^2 = 6^2
(x + 2)^2 + (y + 2)^2 = 6^2
(x + 2)^2 + (y + 2)^2 = 36. your answer
hope this helped, blessings! :)
