<h3>Remember these laws of integers:</h3>
- (+)(-)=(-)
- (-)(+)=(-)
- (-)(-)=(+)
- (+)(+)=(+)
Answer:
Step-by-step explanation:
Complementary angles mean two two angles sum with equal 90 degrees. Therefore you would need to create an equation to solve for the value of x.
4x+3x+13=90
-13 -13
7x=77
/7 /7
X=11
Now plug in the value of x.
A=4(11) B=3(11)+13
A=44. B=33+13
B=46
Angle a is the smaller angle and measures at 44°
Exp prob (red) = 24 / 60 = 4 / 10 = 2/5
Theoretical prob (red) = (1/2)
Exp prob (blue) = 14 / 60 = 7 / 30
Theoretical prob (blue) = 1/6
Exp prob ( yellow) = 22/ 60 = 11/30
Theoretical prob ( yellow) = 2/6 = 1/3
The answers are the second, fifth, and sixth.
