<span>According to trigonometric the formula for sin is
sin = opposite/hypotenuse.Sin is defined as the ratio of sides of a right angled triangle.Hypotenuse is the is the longest side of a right-angled triangle,which is the side opposite of the right angle.So the the hypotenuse is clearly 1.3, so you divide 0.5/1.3
Hence the answer is around 0.38
The result is Angle2..</span>

Answer:
Ann - 61 kg
Beth - 58 kg
Celine - 54 kg
Step-by-step explanation:
We use Algebra to solve this. We give unknown to one of them. I have decide to use x here and give it to earn.
Ann = x
Ann + beth = 119 meaning ( 119 - x) = beth
beth = 119 - x
celine + ann = 115 meaning(115 - x) = celine
celine = 115 - x
know we know>
Ann = x
beth = 119 - x
celine = 115 - x
and beth + celine= 112 kg meaning =>
119 - x + 115 - x = 112
we collect the like terms. 119 and 115 cross the equal sign to the other side.
-x-x = 112 - 119 - 115
-2x = -122
-2x/-2= -122/-2
x = 61
therefore ann has 61 kg
beth has 119 - 61 = 58 kg
celine has 115 - 61 = 54 kg
