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

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

Step-by-step 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

14

step-by-step explanation:

14 x 3 = 42

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
