Knowing about corresponding angles, we know that m∠d = 70°.
The sum of the measures of the angles d and g is equal to 180°. Or in other words, they are supplementary.
Knowing this, we can use algebra to build an equation and solve for g.
70° + m∠g = 180°
m∠g = 110°
And finally, using the knowledge of vertical lines, ∠g is complementary to ∠e.
So, m∠e is equal to 110°.
