Quadrant of after 360 would the first quadrant.
As the if the cycle of all four quadrant is completed than it becomes zero(0) .
eg.cos 405
cos(360+45)
cos(0+45)
cos45=1/2^1/2
As long as there are no numbers after them the zeros on the right of the decimal don't matter (i.e. 6.3000000=6.3 3.00000=3)
So 81.9=81.90=81.900
Since three of them are the same number there is only one answer left (81.91)
Answer:
Answers: 46, 23, and 111
Step-by-step explanation:
To answer, we need to know the angles. Therefore, give each angle a name. Angle 1 will be x, 2 will be y, 3 will be z. So, using this system of equations:
x=2y
z=y+88
x+y+z=180
Substituting, z = 1/2(x)+88, now plug z into the third equation:
x+1/2(x)+1/2(x)+88=180
this simplifies to 2x+88=180
subtracting 88 from both sides leaves 2x=92
x=46
plug this in to the first equation: 46 = 2y, so y = 23
plug this into the third one leaves z = 111
Hope this helps!
