have a nice day and mark me brainliest! :)
Answer with explanation:
m∠9=80°
m∠5=55°
⇒∠3+∠5=180°----[e║f, and these angles are on the same side of transversal c]
→∠3+55°=180°
→∠3=180° -55°
→∠3=125°
→∠3=∠2-----[Vertically Opposite Angles]
1→→∠2=125°-----[True]
2.→→∠3=55°-----[False]
3.→→∠5=∠8=55°-----[Vertically Opposite Angles]----[True]
4.→→m∠9=m∠12=80°
m∠12=100°-----[false]
5.→→∠12 +∠14=180°-----[Lines e and f are parallel, and d is a transversal.]
→→80°+∠14=180°
→→∠14=180°-80°
→→∠14=80°------[True]
6.→→∠14 +∠16=180°----[Interior Angles on the same side of transversal]
→100°+m∠16=180°
→m∠16=80°-----[True]
→→→1,3,5 and 6 are Correct.
