Answer:
II.
1. 77
2. 103
3. 103
4. 103
5. 103
Step-by-step explanation:
II.
m<4 = m<5 (If two parallel lines are cut by a transversal, Alternate interior angles are congruent)
Thus, 5x+7 = 7x-21
21 + 7 = 7x - 5x
2x = 28
x = 14
m<4,m<5 = 77
1. m<1 = m<4 (Vertical Angles are congruent)
thus, m<1 = 77
2. m<2 is a supplement of m<1
m<2 + m<1 = 180
m<1= 77
thus, m<2= 103
3. m<3=m<2 (Vertical Angles are congruent)
thus, m<3 = 103
4. m<6 corresponds to m<2
thus, m<6 = 103
5. m<7 = m<6 (Vertical Angles are congruent)
thus, m<7 = 103
