The length of the side EF will be 18 inches as the sides opposite to the equal angles are also equal.
We are given a triangle EFG.
In this triangle, we can see that:
∠ E = ∠ F = 23°
Now, we know that the sides opposite to the equal angles are also equal.
So, the side opposite to angle E is GF
And the side opposite to angle F is EF.
This means that EF will be equal to GF.
EF = GF
Now, we are also given that GF = 18 inches.
So, EF will also be:
EF = 18 inches.
Therefore, we get that, the length of the side EF will be 18 inches as the sides opposite to the equal angles are also equal.
