180 - 108 = 72
180 - 72 -43 = 65
triangle on the left
Angles = 43,65,72
triangle on the right
180 - 65 = 115
180 - 115 - 35 = 30
so angles of triangle on the right = 30, 35, 115
x = 30 (vertical angles with the other angle of triangle on the right)
5 wholes = 5
2 fifths = 2/5
5 - 2/5 = 4 3/5 (4 and 3 fifths)
Answer = 4 3/5
Check work:
4 3/5 + 2/5 = 5 (wholes)
Answer:
1 / 5040
