Geometry. i'm really struggling with this.

The measure of Angle G is 62.5°.

Step-by-step explanation:

Given:

Δ EFG is an Isosceles Triangle.

EG = EF

m∠ E = 55°

To Find:

m∠ G = ?

Solution:

Δ EFG is an Isosceles Triangle. ........Given

EG = EF                                   ..............Given

∠ G = ∠ F = x (say)              ..................Isosceles triangle property

Now in Δ EFG we have

∠ E + ∠ G + ∠ F = 180° .......... Angle sum property of triangle

On substituting the values we get

The measure of Angle G is 62.5°.
