(Answer 2,770) (estimation: 3,000)
1) "a" and 60° are vertical angles, hence equal. a = 60°
2) "b" is the supplement to 60°, so is 180° - 60° = 120°. b = 120°
3) "d" is the supplement to 65°, so is 180° - 65° = 115°. d = 115°
4) "e" and 65° are vertical angles, hence equal. e = 65°
5) "g" is the supplement to 55°, so is 180° - 55° = 125°. g = 125°
6) "h" and 55° are vertical angles, hence equal. h = 55°
Y = -8 because 1/2 * -4 is equivalent to -2 and then -2 minus 6 is negative 8 so your answer y=8

HOPE it will be right... Good luck
Answer:
1/4845
Step-by-step explanation:
The probability of selecting a defective cog first is
1/5
The second cog is
3/19
The third cog is
1/9
And the fourth cog is
1/17
Multiplying these together we get
1/5 * 3/19* 1/9 * 1/17 = 1/4845
