Answer:
3
Step-by-step explanation:
sec(17) = sec(90-73) = cosec(73)
tan(68) = tan(90-22) = cot(22)
cos(44) = cos(90-46) = sin(46) hence,
{cos(44)^2} = {sin(46)^2}
Using above results given equation becomes
=1+1+{sin(46)^2} + {cos(46)^2}
=1+1+1
=3
Trigonometric Identities used :
sec(90-x) = cosec x
tan(90-x) = cot x
cos(90-x) = sin x
[cos x]^2 + [sin x]^2 = 1
