Answer:
m∠1 = 20°
m∠4 = 110°
Step-by-step explanation:
m∠1 + 70° = 90°
m∠1 = 20°
70° + m∠4 = 180°
m∠4 = 110°
Answer:
[tex] \boxed{m \angle1 \: = 20} \\ \\ \boxed{m \angle4 = 110}[/tex]
Step-by-step explanation:
[tex]m \angle1 \: =90 - 70 = 20 \\ m \angle4 = 360 -( 180 + (180 - 110)) \\ m \angle4 = 360 - 250 \\ m \angle4 = 110[/tex]
