The sum of the interior angles of a hexagon is 720 degrees, and there are two right angles. The sum of the known angles is 573, so 720-573 is 147. Pick c.
LCM is found by finding the factors of both and making sure that both are inthere 9=3 times 3 12=2 times 2 times 3 common one is 3 so we have to have at least 2 threes and 2 twos 2 times 2 times 3 tiimes 3=36 answer is 36
