can anyone answer this question?
I don't get it, it's pretty difficult.

Answer:
Step-by-step explanation:
sin = opposite / hypotenuse
sin x = 36 / 45
sin x = 4/5
the least common number for 36 and 45 is 9
36/9=4
45/9=5
Answer:
sin X = 4/5
Step-by-step explanation:
Hey common, I quite simple. When ever you get a question of this magnitude always remember SohCahToa.
SOH = opposite / hypotenuse
CAH = Adjacent / Hypotenuse
TOA = Opposite / Adjacent
From the question:
Sin X = Opposite / Hypotenuse.
(The opposite of angle X is 36°) over (Hypotenuse - the longest side = 45)
sin X = 36/ 45
Divide through by 3
sin X = 12/15
Divide through by 3 Again
Sin X = 4/5
Hope that makes it simple for you
