Answer:
Answer → 63°
Step-by-step explanation:
» m<3 and m<4 are supplementary angles.
☑ Supplementary angles are angles that measure up to 180°
[tex]{ \tt{m \angle 3 + m \angle 4 = 180 \degree}} \\ { \tt{117 \degree + m \angle 4 = 180 \degree}} \\ { \tt{m \angle 4 = 180 \degree - 117 \degree}} \\ { \tt{m \angle 4 = 63 \degree}}[/tex]
