Answer:
Explanation
If we assume that angle GHI is a straight line and angles G and I are adjacent to it, then we can say that:
G + I = 180 degrees
If the angle GI is 80 degrees, then we have:
G + 80 + I = 180
Simplifying, we get:
G + I = 100
Without knowing the specific relationship between the angles G, H, and I, it is not possible to determine the measure of angle GHI with just the information that angle GI is 80 degrees.
