Answers & Comments
Answer:
1. 60°
2. 125°
3. 50°
4. 60°
5. 110°
6. 80°
Step-by-step explanation:
1.
m<6 = m<3 = 60°
2.
m<3 + m<5 = 180°
so m<5 = 180° - m<3
= 125°
3.
m<3 = m<2 = 50°
m<5 = 180° - m<3
= 130°
m<7 = 180 - <5
= 50°
4.
m<4 = m4 = 120°
m<6 = 180° - m<4 = 60°
5.
m<6 = 180° - m<8 = 70°
m<4 = 180° - m<6 = 110°
6.
m<5 = 180° - m<7 = 80°
m<1 + m<3 = 180°
m<3 + m<5 = 180°
so m<1 = m<5 = 80°
