Sagot :

Given the shown triangle

Using cosine laws

[tex]c^2=a^2+b^2-2abcos(C)[/tex][tex]c^=\sqrt{a^2+b^2-2abcos(C)}[/tex]

where

b=

[tex]b=\frac{21sin(81)}{sin(9)}[/tex][tex]b=132.59[/tex]

then

[tex]c=\sqrt{a^2+b^2-2abcos(C)}[/tex][tex]c=\sqrt{21^2+132.59^2-2(21)(132.59)cos(90)}[/tex][tex]c=134.24[/tex]

WS= 134.24
