Answer:
1. m∠8 = 30° 2. m∠5 = 27° 3. m∠1=m∠8 4. m∠3=m∠7
m∠6 = 180-120
m∠6 = 60
if m∠1 is 120 and m∠6 is 60, it is true because m∠2 and m∠1 are linear pairs/supplementary, so when you set them = 180 and solve for m∠2, you'll get 60. and because corresponding angles are equal and angle 6 and 2 corresponds, m∠6 will be the same measure as m∠2
Explanation:
- because corresponding angles are equal in measure.
- because alternate interior angles are equal in measure
- because they alternate
- because they correspond
- because co-interior angles are supplementary, subtract 120 from 180 to get m∠6.
