To find BC:
• we can see that there is a right angle triangle
• to make it easier use the concept
SOH: Sine° = Opposite/ Hypo
CAH: Cos° = Adjacent/ Hypo
TOA: Tan° = Oppo / Adjacent
(look the CAPITAL letter there, it'll helps us later)
So, we are given: 16 (hypo)
we want to find BC : Opposite
WE HAVE (H) and (O) thefore we use SOH
sine 5° = BC/ 16
(then move 16)
sin 5° x 16 = BC
