Lines e and f are parallel. the m< 9=80° and m< 5=55°. which angle measures are correct? check all that apply.

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.

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8

question

given the diagram below, what is md?

the sum of the interior angles is 360°

take away from 360 the sum of the knows angles and you will have the angle d.

360 - 108 - 108 - 72 = 72°
