Answer
m<3 = 49°
Step-by-step explanation:
It is given that,
M∥n, m∠1 = 50°, m∠2 = 48°, and line s bisects ∠ABC
m<DEF = m<1 + m<2 = 50° + 48° = 98°
Corresponding angle of <DEF is equal to <ABC = 98°
To find m<3
< 4 = <5 = 98/2 = 49° (Since line s bisects ∠ABC)
Therefore,
m<3 = 49° (< 4 and <3 are vertically opposite angles)
