Chapter 2 - Section 2.1 - The Parallel Postulate and Special Angles - Exercises: 4b

Answer

m$\angle$8=110.8$^{\circ}$

Work Step by Step

If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent. Since we are given that lines l and m are parallel, and $\angle$4 and $\angle$8 are corresponding angles, we know that $\angle$4 and $\angle$8 are congruent. Since $\angle$4=110.8$^{\circ}$, $\angle$8 must also be 110.8$^{\circ}$.
