Answer:
Step-by-step explanation:
Sin26=cos64
Cos64/sec64
Cos64/1×cos64
Cos^2 64
Similarly it is sin^2 64
Therefore when we add both 1 will come
Hope it helps

Lhs =sin26/sec64 +(cos26/cosec64)
sin26/sec(90-26) + cos26/cosec(90-26)
sin26/cosec26 +cos26/sec26
sin26*sin26+cos26*cos26
sin^2(26)+ cos^2(26)
=1
Hope It helps you
