Can some help me with This

Answer:
28 : 53
Step-by-step explanation:
LK = 90°
JI = 53°
IK = 45°
KJ = 28°
-------------------------------------------------------------------------------------------
The ratio represents the sine of ∠ I is :
Sin ∠I = [tex]\frac{IK}{JI} =\frac{28}{53}[/tex]
--------------------------------------------------------------------------------------------
Step One: Reduce the fraction
This fraction is already reduced so no further work is needed
Step Two: Rewrite as a ratio
28/53 = 28:53
