Question

find the value of cos 60° geometrically

Answer 1

hey ..!!

here the ans is...

consider a right angled Δle with A at 60°, BC =1 cm and AB=2 cm
so,∠ BAC=60°

now, cos 60°=BC/AB=1/2



cosec 60°=BC/AB=2/x

by applying pythagores theorem,

AB²=AC²+BC²
 2²  =x² +1²
 4   =x² +1
 x² =3
x  =√3

hence,
        cosec 60°=AB/AC=A2/√3

hope my ans helps u dear..

              ^-^

plz...make my ans as brainliest if i deserve...
