In order to find G, use the formula G = 180 - 2(43).

This formula represents that there is a sum of 180 degrees total in a triangle, and that an isosceles triangle has 2 equal angles (E and F) and 1 other angle (G). By subtracting the total angles by the 2 equal angles, you get the one other angle, which is G.

Solve for G to get your answer.

G = 180 - 2(43)
G = 180 - 86
G = 94

Therefore, G is equal to 94 degrees.

Proof: 94 + 43 + 43 = 180
