All the angles in a triangle have to add up to 180 degrees. So far, we have a 120 degrees made up by 2 angles (meaning each angle is 60 degrees) which means the missing angle [g] is 60 degrees. However, we haven't finished the problem. We also have to work of 1,100/9 to the power of 60 (which is g). 1,100 divided by 9 is 122.2 (repeating bar over the two after the decimal point). 122.2 to the power of 60 would be 1.675994e+125 degrees. But, this feel too big of an answer for this problem, so I assume ^ (to the power of) was meant to be* (multiplied by). 122.2 x 60 = 73.32 degrees.
