Answer:
8. m∠1 = 64, m∠2 = 26, m∠3 = 36
9. m∠1 = 73, m∠2 = 58, m∠3 = 107, m∠4 = 49, m∠5 = 131
10. m∠1 = 34, m∠2 = 52, m∠3 = 38, m∠4 = 94, m∠5 = 56, m∠6 = 38
11. m∠1 = 62, m∠2 = 71, m∠3 = 109, m∠4 = 35, m∠5 = 109, m∠6 = 29, m∠7 = 47, m∠8 = 62
Step-by-step explanation:
8. m∠1 = 180 - (75 + 41) = 180 - 116 = 64
m∠2 = 90 - 64 = 26
m∠3 = 90 - 54 = 36
9. m∠3 = 180 - 73 = 107
m∠1 = 73
m∠2 = 180 - (73 + 49) = 180 - 122 = 58
m∠4 = 49
m∠5 = 180 - m∠4 = 180 - 49 = 131
10. m∠6 = 90 - 52 = 38
m∠3 = m∠6 = 38, m∠2 = 52
m∠5 = 180 - (86 + 38) = 180 - 124 = 56
m∠1 = 90 - 56 = 34
m∠4 = 180 - (34 + 52) = 180 - 86 = 94
11. m∠2 = 71
m∠3 = m∠5 = 180 - 71 = 109
m∠1 = 180 - (47 + 71) = 180 - 118 = 62
m∠4 = m∠2 - 36 = 71 - 36 = 35
m∠6 = m∠2 - 42 = 71 - 42 = 29
m∠7 = 47
m∠8 = m∠1 = 62
