Answer:

∠ GEF = 35°

Explanation:

∠ DEG and ∠ GEF are a linear pair and sum to 180° , that is

∠ DEG + ∠ GEF = 180°

145° + ∠ GEF = 180° ( subtract 145° from both sides )

∠ GEF = 35°

--------------------

given 2 points (x₁, y₁ ( and (x₂, y₂ )

then calculate the distance d between them using the distance formula

d =
\sqrt{(x_(2)-x_(1))^2+(y_(2)-y_(1))^2 }
