Answer:
g = 123
k = 81
h = 57
m = 99
Explanation:
Because the angles h and g are complementary(two angles that add up to 180 degrees) and you know that g = 123, you can find h by subtracting 123 from 180. 180 - 123 = 57. So h = 57. You could do the same thing with m. Since k = 81, you subtract 81 from 180, leaving you with 99. So m = 99.
