I assume you mean EFG are the interior angles you need to find and efg are the sides( must be sides as they do not add to 180). Use law of cosines. Need to change to your letters; twice. Then for third angle subtract from 180 degrees I assume you mean e = 29 ( you need to be more careful in mathematics ) DEGREE MODE!

f^2 = g^2 + e^2 - 2ge cos(F)

15^2 = 18^2 + 29^2 - 2(18)(29) cos(F)

225 = 1165 - 1044(cos F)

-940 = -1044(cos F)

0.90038 = cos F

arcos(0.90038) = F

F = 26 degrees

g^2 = e^2 + f^2 - 2ef cos(G)

18^2 = 29^2 + 15^2 - 2(29)(15) cos(G)

324 = 1066 - -870(cos G)

-742 = -870(cos G)

0.85287 = cos G

arcos(0.85287) = G

G = 31 degrees

Now just subtract these answers from 180 degrees for E

180 - 26 - 31

E = 123 degrees

F = 26 degrees

G = 31 degrees

How do you solve triangle EFG given that g equals 5 e equals 7 and G equals 43?

It depends on what you mean by "solve". This is the "ambiguous" case so that there are two possible solutions depending on whether F is acute or obtuse. Assuming one or the other, the sine rule will give you angle E and so angle F can be calculated and, from that, side f.

Is EFG HJK?

The question "Is EFG HJK" lacks context, making it difficult to provide a definitive answer. If EFG and HJK are identifiers for specific entities, comparisons, or concepts, additional information is needed to understand the relationship between them. Please provide more context or clarify what you mean by "EFG" and "HJK."
