Step-by-step explanation:
Using sinus law
sin(A) /a = sin(B) /b = sin(C) /c
Where smale letters indicate the sides
For this question :
(sin(90)*12)/sin(53)=15
To convert to a decimal, you can do long division, dividing 5 into 4. Or, you can realize 5/4 = 1 and 1/4, = 1.25. 125/100 is easier to see as a decimal. 125/100 = 1 and 25/100.
