Answer:

62

Explanation:

Use the Law of Sines: sinA/a = sinB/b = sinC/c, where A, B, and C are the angles and a, b, and c are the sidelengths opposite of their corresponding angles.

If angle G = 66 and angle H = 30, then angle F = 180-66-30 = 84 degrees.

Therefore sin84/67 = sin66/g.

Multiple both sides by g and divde by sin84/7 to get

g = sin66/(sin84/67) = 61.5... which is about 62 inches.
