Answer:
m∠6 = 117°
m∠7 = 63°
Step-by-step explanation:
It's given that a║b and m∠3 = 63°
Since, ∠3 and ∠6 are the consecutive interior angles,
m∠3 + m∠6 = 180°
63° + m∠6 = 180°
m∠6 = 180° - 63°
= 117°
Since, ∠3 and ∠7 are the corresponding angles,
Therefore, ∠3 ≅ ∠7
m∠7 = m∠3 = 63°

n= 2/-7
2/n = -7
Multiply by n: 2= -7n
Divide by -7: n= 2/-7, or n= -0.286
F. right angle is correct
