Question

COS 45°/

sec 30° + cosec 30°​

Answer 1

Step-by-step explanation:

cos45°/(sec 30° + cosec 30°)

=cos45/(1/cos30+1/sin30)

=cos45cos30sin30/(sin30+cos30)

=(1/root2 * root3/2 *1/2 )/(1/2+root3/2)

=(root3/4root2)/(1+root3)/2

=( root3/2root2(1+root3)) *(root2(root3-1)/root2(root3-1)

=root6(root3-1)/(4(3-1))

=root6(root3-1)/8
