heya..!!!!
here, alpha = ∅
3tan∅ = 4
=> tan∅ = 4/3 = perpendicular/base
perpendicular= 4 , base = 3
h² = 4² + 3²
=> h² = 25
=> h = 5
cos ∅ = 3/5 = p/h
=> 1/sec∅ = 3/5
=> sec∅ = 5/3
=> 5/3 - 4/3
=> (5-4)/3
=> 1/3

Hii friend,
Let theta = @
3 Tan@ = 4
Tan@ = 4/3
Under root 1 - Sin@ / 1 + Sin@ = ✓ 1-Sin@ / 1+Sin@ × 1-Sin@ / 1 - Sin@
= (1-Sin@)/ Cos@
= 1/Cos@ - Sin@/Cos@
= Sec@ - Tan@ [ 1/Cos@ = Sec@ and Sin@/Cos @ = Tan@]
= ✓ 1+ Tan²@ - Tan@
= ✓1 + (4/3)² - 4/3
= ✓1+16/9 - 4/3
= 5/3 -4/3
= 5-4÷3 = 1/3
HOPE IT WILL HELP YOU..... :-)
