Question 1210455
The drawing is not to scale because of typos, but hopefully my calculations were typo-free.

)}}} Consider right triangles {{{KAS}}}, {{{LSB}}}, and {{{LBO}}}. We know that {{{SB+ BO=8.2m}}}.
{{{L*tan(28^o)+L*tan(35^o)=8.2m}}}   {{{L(tan(28^o)+tan(35^o))=8.2m}}}  {{{L=8.2m/1.231917=6.656293m}}}
The distance between Lina and the Orb is
{{{L/cos(35^o)=6.656293m/0.819152=highlight(8.126m)}}}
The distance between Kai and the Orb is
{{{L/cos(42^o)=6.656293m/0.743145=highlight(8.957m)}}}
If Orin magically lifts the Silver Orb 1.5 meters higher, it will be at point {{{"S'"}}}, 1.5 meters above {{{S}}}.
In triangle {{{KAS}}}, {{{AS=L*tan(42^o)=6.656293m*0.900404=5.993353m}}}.
In the new right triangle {{{"KAS'"}}}, {{{"AS'"=5.993353m-1.5m=4.493353m}}}.
The length of side {{{KA}}} is still {{{6.656293m}}}.
Kai's distance to {{{"S'"}}} in meters can be calculated from the Pythagorean theorem as
{{{"KS'"=sqrt(6.65629^2+4.493353^2)=8.030968413}}} {{{highlight(8.031m)}}} when rounded to 3 decimal places. That puts Kai closer to the Silver Orb than Lina.
Orin could instantly calculate all that. His magical powers make him a geometry and trigonometry wizard too.
