Answer:
7
Step-by-step explanation: calculate the prime factors of 7 and 21, than find the greatest common factor
1) Now,
a + 27° = 90° (right angle triangle)
◆ a = 63°
2) Now,
b + b + b = 90° (right angle triangle)
or, 3b = 90°
◆ b = 30°
3) Now,
c + c + 40° = 90° (right angle triangle)
or, 2c = 90° - 40°
or, c = 50°/2
◆ c = 25°
4) Here,
◆ e = 41° (vertically opposite angle)
◆ f = 82° ( vertically opposite angle)
Now,
d + e + f = 180° (straight angle)
or, d + 41° + 82° = 180°
or, d = 180° - 123°
◆ d = 57°
Then,
◆ g = d = 57° (vertically opposite angle)
It is all correct answer...
I hope u understand...
Thank you ♥♥ my cutie...

22. P(n > 3) = P(4)+P(5) = (4+5)/30 = 9/30 = 3/10
23. The game isn't fair because there as many even numbers as there are odd numbers on a die. You get double the points he gets at the same chance!
