→Scam = Report ​

Answer 1

Answer:

i.) 40

ii.) 90

iii.) 50

iv.) 40

v.) 45

vi.) 70

vii.) 60

viii.) 55

ix.) 30

Step-by-step explanation:

Sol. ii.) 45 + 45 + x = 180

x = 180 - 90

x = 90

Sol. iv.) x + x + 100 = 180

2x + 100 = 180

2x = 80

x = 40

Sol. v.) x + x + 90 = 180

2x = 90

x = 45

Sol. vi.) x + x + 40 = 180

2x = 140

x = 70

Sol. vii.) 120 + opposite missing side = 180

opposite missing side = 180 - 120

= 60

so x = 60

Sol. viii.) 110 + opposite missing side = 180

opposite missing side = 180 - 110

=70

x + x + 70 = 180

2x = 180 - 70

2x = 110

x = 55

Sol.xi.) 30 = opposite angle[vertically opposite angle]

hence x = 30
