Question

What are the angle measurements of 1,2,3,4,5 &6?

Answer 1

I:40,ii:65,iii:75,iv:40,v:75,vi:15

Explanation:

75+65+i=180

140+i=180

i=180-140

i=40

i=iv=40(alternative angle)

65+40+v=180(straight line angle)

105+v=180

v=180-105

v=75

v=iii=75(alternative angle)

90+75+vi=180

165+vi=180

vi=180-165

vi=15

40+75+ii=180

115+ii=180

ii=180-115

ii=65
