let me solve....wait:)
ok
good question @koli123able
sry but my answer comes 5.79:) let me show it
ok
how??
c^2=a^2+b^2-2ab cos c c^2=10^2+9^2-2*10*9* cos35 c^2=181-180*0.8191 c^2=33.5526 c=5.792:)
how did 35 degrees come..it was not in the question
is there any formula for calculating c
@koli123able actually the angle 55 is given North-East ,in direction angle is measured only from North and South directions only:)
so 90-55=35:)
okay
